CS2 Pets Explained: Egg Hatch Time, Chick, HatchBook

Counter-Strike 2 has pets now. Chickens, to be exact. They arrived on 22 September 2026 inside the Rush Hour update, and Valve did not write a single line about them. Players found out when their Weekly Care Package offered a Chicken Egg instead of the usual case or skin. Three weeks on, the first eggs have hatched and the chicks are walking around on main menus. This post explains what the egg is, when it hatches, what the chick stage looks like, what the bird needs from you, and what the game files say about the parts that have not happened yet.

What Actually Shipped

The Rush Hour announcement covers the new 3v3 Rush mode, the Premier map picks, silent reloading, crosshair changes and the return of clan tags. The release notes that went up a minute earlier list dozens of changes. The only chicken in either document is one line: chickens now take damage from the Zeus. Pets, eggs and feed appear nowhere. The follow-up updates on 23 and 24 September fixed reload exploits and crosshair bugs and again said nothing about pets, and no patch note since has mentioned them either.

Within an hour of the update the first egg turned up on Reddit, dataminer Gabe Follower tied it to the pet files he has been tracking since 2023, and Thour posted the Pet Book images from the game files. So this is not a leak or a test. It is live, it is just unannounced.

How to Get a Chicken Egg

You do not buy the egg and you cannot trade for one. It shows up as one of the four items in your Weekly Care Package, the reward you unlock by ranking up once a week with Prime Status. Normally you pick two of the four. The egg’s card reads “Untradable, consumes both of your rewards”, so taking it means giving up the case and the skin.

Not everyone sees an egg, and it is not only about Prime. No Prime means no care package and therefore no egg, but several members of our Discord and a well-upvoted Reddit thread reported a package with Prime and a rank up that simply had no egg in it. Three weekly resets later that is still how it works. Eggs kept appearing (members claimed them on 26 and 28 September, and one chick hatched as late as 13 October), but on 9 October one of our regulars opened his third package in a row without one. The egg is a possible slot in the package, not a guaranteed one.

After you claim it, the egg does not go into your Steam inventory. It sits in a nest beside your agent on the main menu, with the tooltip “Your egg will hatch soon”. Click it and it wiggles.

Playing in a party? The main menu only shows the party leader’s pet, and you can only open your own pet’s menu when you play solo or host the lobby. Claiming a pet item while you sit in someone else’s party takes you out of that lobby.

How Long Does the Egg Take to Hatch?

About a week, and you do not have to guess the day. The egg’s tooltip in the English localisation file says: “Your Egg is not ready to hatch yet. It will hatch in a week or so from when you got it.” The exact date is printed on the cover of your HatchBook, next to the word “Hatches”, and it is set the moment you claim the egg. It held up: two members who claimed on launch day both hatched on 29 September, and one HatchBook printed the exact moment, 00:53 GMT.

The ring around the egg on the main menu is a progress timer. It fills according to a growth percentage that the game asks the item server for, and the menu only draws it, so there is nothing on your side that moves it. Redditors tested the obvious ideas anyway: playing matches for XP, keeping the game open, picking up chickens on retakes. None of it did anything, and one player watched the bar move a sliver after about twenty hours. That is exactly what a seven-day clock looks like on day one.

When the day comes, the game plays a “Growth Spurt” notification, “Look! Your egg is hatching! Time to meet your chick.”, with one of two hatching animations picked at random. If you are not online at that moment, nothing is lost: the pet’s stage lives on the item, so the egg hatches the next time you open CS2. One of our members hatched at 00:53 GMT and posted “the little beast finally hatched” five hours later, chick already walking.

One warning from the files: there is an “Unhatched” notice for an egg that ran out of food, with the line “Never loved. Never hatched. Those two are related.” The menu’s food warnings only start after hatching, and nobody has reported an expired egg, so an egg appears to come with enough food to reach the hatch.

Egg Colours and Rarity

Eggs come in different colours. Reddit has shown white, brown speckled, blue, pale green and pink eggs, and the one in the nest screenshot above, from our Discord, is pale green. Naturally the first question was whether the colour means anything, and a few players have posted “my egg is blue rarity” as if the game had graded it.

It has not. The item schema gives every pet item the same rarity value, “rare”, which is the blue Mil-Spec band that weapon skins use. That is why the egg card shows a blue rarity tint for everyone, no matter what colour the shell is. Nothing in the files links shell colour to a breed or a skin either. The files hold one chick model, and the hatches so far have shown it in two colours: the yellow chick almost everyone got, and a white one. Two of our members hatched on the same morning, one yellow and one white, and the white one’s owner asked the obvious question in all caps. Nobody can answer it yet. Breed and colour only show once the chick becomes a pullet, which the game’s own milestone text describes as “colors coming in”, so whether a white chick hints at a white hen is one of the things the first pullets will tell us.

The Chick Stage, In Game

Once the egg hatches, the nest disappears and the chick walks around the main menu floor next to a red feeder with a glass jar of grain on top. Hover over it and a small bar appears: a round growth timer, then buttons to zoom in, inspect, rename, open the photo booth and open the HatchBook. The timer’s tooltip during the whole chick stage reads “Your chick will be a pullet soon. Enjoy the little one, and take some photos.” Do not read a date into that: it is the chick stage’s fixed line, the same way the egg’s line was “Your egg will hatch soon”, and it says the same thing on day one and on day seventeen.

Naming works right there on the menu. The pencil opens a text field with the current name already in it, “Pet Chick” until you change it, with a tick to confirm, a cross to clear and an arrow to back out. The limit is 20 characters and you do not need a Name Tag, the menu uses a built-in one. The game files say the name can be changed once per growth stage. The inspect view then shows the name in quotes under “Pet Chick”, with the hatch date underneath. Members have gone with “Pompidou”, a girlfriend’s name, and “used”.

How long does the chick stage last? Longer than a week, and longer than the egg. The launch-day chicks were still chicks on 16 October, seventeen days after hatching, with no growth notification in sight. The 22 days that several sites quote remains unsourced, but it is at least not contradicted. We will put the real number here the moment the first pullet appears.

From Egg to Hen

The pet grows through four stages, each with its own fixed line on the main menu and a “Growth Spurt” notification at the transition.

Stage	What the game says	Seen in game
Egg	“Your egg will hatch soon.”	Yes, 22 to 29 September
Chick	“Your chick will be a pullet soon. Enjoy the little one, and take some photos.”	Yes, since 29 September, still running on day 17
Pullet	“Growing fast, colors coming in, and cleared to deploy with you. Get your photos in now. It won’t stay this size for long.”	Not yet, as of 16 October
Hen	“A full-grown hen. You raised it well. Enjoy your time together.”	Not yet, as of 16 October

The item schema stores a “next upgrade date” on the pet, which points to growth on a timer rather than on matches played. How long each stage lasts is not in the client files. Many sites quote 22 days as a chick, 28 as a pullet and 90 as a hen, 140 days in total, but we could not trace those numbers to any source. There is also a line that reads “You cannot bid on this offer because you already own a pet”, which tells us two things. One pet per account, and a second route exists in the code next to the weekly drop: a bidding offer in the Armory that hides itself once you own a pet. Whether it goes live is unknown.

Feeding Your Chicken

The pet is not a one-time unlock. Chicken Feed is a separate item, and its description is blunt: “Feed your pet to keep it around.” The files carry a food expiration date on the pet and a full set of notifications for when you let it run out.

Feed comes from the Weekly Care Package, the same weekly reward that gave you the egg. The care package code prices it exactly like the egg: claiming feed uses both of your two picks, so a week you feed your chicken is a week without a case or a skin. When your food will not last until the next growth stage, the XP tooltip swaps its usual care package line for “Get feed for your pet the next time you rank up!”. That points at the same package, not at a second source. There are two products, a chick starter bag and an adult chicken bag, both from the fictional Sunnyside brand.

How often you actually need it is the open question, and the first three weeks say: less often than people feared. The member whose chick hatched on 29 September had not been offered feed by 16 October, and his menu had not warned him either. “2 weeks and they didn’t give me food” was his summary. So a chick comes with more than two weeks of food, and the package apparently only puts feed in front of you once the bird needs it, although nobody has reached that point yet. The glass jar on the feeder was close to empty by day 17, so the jar itself is probably the intended way to keep an eye on it.

The menu warns you twice. The first warning, “Your pet is running low on food”, is decided by the item server. The second one is decided by the menu code itself: it compares the food expiration date with the next upgrade date, and if the food runs out before the next growth stage it shows “More feed for your pet is available in Weekly Care Packages”. In other words, the game tells you when your current bag will not get the bird to its next stage.

Stop feeding and the pet leaves. The notification is titled “Retirement”, and the game picks one of three lines: “Your pet has accepted a position elsewhere. The offer included meals.”, “Turns out chickens need food. Who knew?”, or “In your defense, it never once complained.” An egg you never feed gets its own title, “Unhatched”. Pets also age out at the end: “A Life Well Lived” tells you the bird no longer needs you and that you can revisit your time together from your profile card. Whether Valve will also sell feed is not in the files we could read.

The Three Breeds and 40 Base Colours

The pet definitions name three breeds: the Catalana (the standard Counter-Strike chicken, named after a Spanish breed in the item schema), the Polish (the one with the feather crest) and the Silkie (the fluffy one). Mapper Lillykyu was the first to run the models through a viewer and counted 34 chickens plus the chick, which is where the number 35 that most sites use comes from. The material files hold more: 15 Catalana, 12 Polish and 13 Silkie base colours, 40 in total.

Valve’s own material names read like a poultry catalogue: black with white head, light blue and red, orange with blue neck, and on the Silkie side leopard, tiger, splash and red beetle. Those names are base colours, not fixed ones. On 31 of the 40, the material files shift the hue per chicken, and most also vary the saturation, brightness or contrast per bird. Valve set a separate range for each colour: the Catalana Blue only moves between 119 and 157 degrees on the colour wheel, so it always stays blue, while the Polish Pink, the Silkie Red and the Silkie Leopard can land anywhere on the wheel. Colours with a pattern layer, such as the spots on the Leopard, can also tint that layer separately and place it in one of four positions, and some birds get a rainbow sheen on their feathers of varying strength. Only six base colours have no per-chicken values at all: the Catalana Red Yellow Gradient and White Tan Head, and the Silkie Black, Brown, Brown with Black Head and Tiger. So two chickens with the same colour name can look clearly different.

Which breed and base colour you get, and with what odds, is not in the files, so any percentage you see elsewhere is not confirmed. Where the per-chicken values come from is covered in the next section.

We rendered every base colour straight from the game models. The renders show each colour without any per-chicken shift and use the base colour texture only, so the spot pattern the game lays over the Silkie Leopard and Splash is missing here. Your own chicken can look different.

All 15 Catalana Chicken Colours

All 12 Polish Chicken Colours

All 13 Silkie Chicken Colours

What Is the Pet Seed?

“Pet seed” has become a search term of its own, so here is what it is and what it is not. The item schema defines an attribute called “pet seed” on the pet item, next to the “set item texture seed” that weapon skins use for their paint seed and the “keychain slot seed” that charms use. It is a hidden number rolled when the item is created. It is not shown anywhere in the client: the inspect view prints only the name and the hatch date, and the HatchBook does not print it either. The schema even borrows the charm’s label for it, “Charm Template”, which suggests a display string that nobody got round to writing.

What the seed does is the interesting part, and the honest answer is “probably the colour shift”. The material files give 34 of the 40 base colours a per-chicken range for hue, saturation, brightness, pattern tint and pattern position, and the seed is the only per-item number on the pet that could drive those. That link is not written down anywhere we can read, and nothing in the files maps a seed to a breed or a base colour. So there is no “rare seed” list, no seed you can check for before the pullet stage, and nothing you can do about the one you got. If a site shows you a seed table for chickens, ask where the numbers came from.

The HatchBook, Page by Page

Every egg comes with a book. The files call the folder Pet Book and the menu calls it “The HatchBook”, subtitled “The life and times of” your pet’s name. While the egg sits in its nest the cover shows “Hatches” and the date. After the hatch, the book opens from the hover bar on the main menu or from inside the photo booth, with a Library panel on the right that reads “Photos you take will appear here” until you take one.

It is a scrapbook, not a progression tree: nine pages across three chapters, Chick, Pullet and Hen, with a small chapter bar under the book to jump between them and a page counter. Here is what the chick chapter looks like once the egg has hatched, from a member’s book opened on day 17.

• Page 1, “Just Hatched”. The game fills this one in for you. It takes two photos of the chick at the hatch, prints the exact moment (“Sep 29, 2026 (0:53:31) GMT”), stamps a pair of inked footprints next to it, and adds one line from a set of eight. Ours got “You made your grand entrance into the world through the aggressive headbutting of a perfectly good calcium sphere.” Others in the files: “Day one. You weighed less than a flashbang and were roughly twice as loud.” and “Smaller than my hand, louder than my headset. We got off to a wonderful start.”
• Page 2, “Early Days” and “Park Life”. Two framed slots with a hint of what to shoot: your chick in your hands, and your chick at the Picnic stage. The slot captions come from the files too, such as “Two species, one questionable idea, off to a running start.” and “Not cleared for the field just yet.”
• Page 3 onwards, free pages. Blank spreads with a layout picker under each page for one, two, three or four photos, and the instruction “Drag and drop to add and remove photos.” You drag them in from the Library.

The pullet chapter asks for the bird in the Warehouse and on a road trip across the map stages. The hen chapter has a wanted poster (“Description: small, armed, unbothered”), a tricks page (“Lightning optional”) and a birthday page that asks for a jump in a party hat with confetti. The last page says The End. Photos are saved as JPG files on your PC as well, with “Copy photo to clipboard” and “Go to library folder” buttons in the viewer. The tooltip for the shelf of old books reads “Books left by your past pets”, so the album is what remains when a chicken retires. Screenshots in this section: l0newo1f, CS2 Central Discord.

The Photo Booth, Every Option

The camera button on the hover bar opens the photo booth: the chick on a stage, a rule-of-thirds grid over it, a shutter button with a self-timer underneath, and a toolbar down the left. Scroll to zoom (the readout under the frame says Zoomed Out, Mid or Closeup), Shift and drag to pan, Shift and right-drag to orbit. These are the tools, in the order they appear, with what a chick can and cannot use.

Tool	Options	At the chick stage
Photo Grid	Grid opacity slider	All
Adjust	Exposure, Saturation, Vibrance, Brightness, Bloom, Contrast, Vignette, Grain, Grime, plus Reset	All
Filters	Normal, Black and White, Sepia, Warm, Cool, Crisp, Moonlight, Silvertone, Psychedelic, with a Filter Strength slider	All
Formats	Square, 4x3, 5x4, 16x9, with a portrait toggle for 3x4, 4x5 and 9x16	All
Poses	Solo, Bird in Hand, Finger, Protect, Take the Knee, Gaze, Big Hug, Overhead, Shoulder, Hawk, Head	Only the first four. The other seven are greyed out with “Not old enough” lines.
Team	CT Agent or T Agent, posing with the bird	All
Stages	Ten plain colours, Photo Studio, Picnic, Warehouse, Baggage, Dust II, Mirage, Inferno, Nuke, Cache, Train, Ancient	Colours, Photo Studio and Picnic. The Warehouse and the maps are locked.
Hats	None, Helmet, Armor Helmet, Alien, Banana, Glasses, Nose Glasses, Party Hat, Sprout, Top Hat, Wizard Hat	All ten
Stickers	Any sticker from your inventory, up to ten per photo, with a search box	All
Lights	A colour picker with RGB and hex input for the stage colour	All
Actions (bottom right)	Sit, Panic, Wag, Dance, Jump, Kick, Fly	Depends on the pose; “Cannot be used with this pose” when they clash
Effects (bottom left)	Confetti, Bubbles, Feathers, Sparks, Beam, Laser, Fire, Lightning, Explosion	Confetti, Bubbles and Feathers work; Fire, Lightning and Explosion unlock through the match events below

Two details worth knowing. Stickers are free to use: the panel says “Stickers placed on photos aren’t applied. They stay in your inventory.” And the agent in the frame is a stock CT or T model, picked with the Team toggle, so a chick can pose with either side no matter what you have equipped.

The locked stages carry their own tooltips. On a chick the Warehouse and the maps say “Older pets can visit locations with you. Finish a match here on official servers to unlock it as a stage.” From the pullet stage the Warehouse opens and the map line shortens to “Finish a match here on official servers to unlock this location as a stage.” That is the clearest sign in the files that the chicken is meant to travel with you.

The flavour writing is the most Valve thing about the whole update. The age locks alone have five different refusals, from “Not old enough for this dangerous pose.” to “Not old enough, unless your pet has faced worse.”, and once the bird outgrows the hand poses the line flips to “Got too big for this pose”.

Will the Chicken Show Up in Matches?

Not as of 16 October 2026, because no pet has reached the pullet stage yet. But the files are much clearer on this than a hint. There is a HUD label for a pet in a match that reads “owner’s name”, so other players see whose bird it is. There is a death notice, “Your chicken has been killed. She was yours for X seconds.” The end-of-match screen places each player’s pet next to their agent, gloves and weapon in the line-up. And the HatchBook has three hidden pages that unlock through achievements named killed-by-burn, killed-by-taser and killed-by-planted-c4: incident reports for a chicken that stood too close to a molotov, a Zeus or the bomb, with lines like “Chicken, extra crispy” and “1 chicken, briefly”. Those same three events also unlock the fire, lightning and explosion effects in the photo booth.

Put together with the pullet milestone (“cleared to deploy with you”) and the map stages above, the picture is this: from the pullet stage the chicken joins you on official servers, it can die there, and dying there is rewarded with a scrapbook page. Which modes, whether it can block a bullet, and what it does all round are questions for the first pullets. The launch-day chicks are the first in line.

What Players Think

The first Reddit thread hit 900 points in a few hours, and the top comment was not about chickens.

“instead of fixing the cheating they gave us this”

- u/IlluminatiMadeMeDoIt on r/cs2

That was the mood in our own Discord as well. In the first ten hours after the update, our general chat produced more than 600 messages, and the egg came back in every one of those hours: should I pick it, what does it do, why is it not hatching. One member did the maths out loud, worked out that the two normal picks were worth about fifteen cents together, and took the egg. Several others followed and compared colours. The criticism aimed at Valve rather than at the chicken: “devs doing this so people forget about the anticheat” was the shortest version, and the egg kicked off a forty minute argument about cheaters in Premier.

By day three the tone had settled into two camps. The larger one calls the chickens a chore that clogs the drop pool (“the chickens are just chores”, “no anti cheat but chickens”). The smaller one is into it, posting “my egg chillin” and asking when it hatches. Clan tags coming back got more genuine enthusiasm than the pets did. The trading channels said nothing at all, which makes sense for an item you cannot trade.

Then the chicks hatched, and the second camp got louder. “The little beast finally hatched” arrived at six in the morning on 29 September, a thread titled “finally my chicken hatched, hes so cute” opened in our media forum a week later asking for name suggestions, and the members who had called it a chore were the ones comparing chick colours. The best bit was not even Valve’s: someone found that the console command cl_ent_scale scales the pet on the main menu, and within days the chat was full of chicks the size of the agent standing next to them. “I think I overfed my chicken” was the caption. At larger values the head starts spinning, which the finder cheerfully reported as a bug.

What We Do Not Know Yet

• How long the chick stage lasts. It is past seventeen days; the first pullet will give us the number.
• How long the pullet and hen stages last. The timers live on the item server, not in the client files.
• What the odds per breed and per colour are, whether the pet seed decides them, and whether a white chick means anything.
• How often the care package offers feed once a bird needs it, and whether feed will be sold.
• In which modes the chicken shows up from the pullet stage, and what it does during a round.
• Whether the Armory bidding offer for pets goes live.

The launch-day chicks should become pullets first. We will update this post when the first one does.

Our Take

People have been asking for a working anti-cheat for a long time, and a pet chicken is not what anyone expected to get instead. There were leaks, so the idea had been teased for two years, but for a game like CS2 it is still a slightly ridiculous concept, and the community’s reaction shows it. We understand the frustration.

It does add something new to a game that had been standing still, and the amount of care in it is hard to dismiss: two feed products with fake packaging, a photo booth with a banana hat, a scrapbook that writes jokes about your chicken, and a main menu that got noticeably sillier the day the eggs hatched. Three weeks in, the chore turned out to be lighter than feared, since nobody has had to spend a package on feed yet. Whether the egg is worth two care package picks is still your call. We have a chicken of our own, and so do plenty of our members. This post exists because they keep posting theirs in the CS2 Central Discord. Come show us yours.
