How long does it take for an egg to become a chicken in CS2?
A CS2 Chicken Egg from the weekly drop hatches in about a week and grows into an adult hen in roughly two months. Every stage with its timing, and what affects it.
Chicken Eggs showed up in CS2 on September 22, 2026, with the Rush Hour update. Valve didn’t mention them in the patch notes at all; players simply found an egg among their weekly drop options. That’s why almost every timing below comes from the game files, checked against the first pets, rather than from an official announcement.
Stages and timing
| Stage | How long | What happens |
|---|---|---|
| Egg | about 7 days | sits next to your agent in the main menu |
| Chick | 22 days | yellow, you can pet it and take photos |
| Pullet | about 28 days | breed and color are revealed, the pet shows up in your lobby and in matches |
| Hen | until the end | new poses and animations |
From the day you claim the egg to an adult hen, that’s around 57 days. Close to two months.
The egg: “a week or so”
The egg’s description says it will hatch a week or so after you got it. The exact date is set the moment you claim the drop, and you can see it in the HatchBook. The first eggs, claimed on September 22–23, hatched on September 28–29, a little faster than a week.
Nothing speeds up hatching. Play ten matches or don’t launch the game at all, it makes no difference: the timers run on Valve’s item server, not in your matches.
From chick to pullet
This one is exactly 22 days; the number is in the game files. The first chicks moved to the next stage on October 20, right on schedule. The tooltip keeps saying your chick will be a pullet soon for the whole stage, so check the HatchBook for the real date.
The pullet is the fun part. Only then do you find out which breed you got (Catalana, Polish or Silkie) and in what color. The egg’s color won’t tell you in advance.
From this stage on you can also bring the pet into a match. Before that, the only chickens you’ll see in game are the regular ones that live on the maps.
From pullet to hen
According to the files, about 28 more days. As of November 3, 2026, nobody has seen an adult hen yet; the first ones should appear around November 17. If Valve changes the timing, we’ll update this article.
No feed, no chicken
Your pet needs Chicken Feed. It only comes from the weekly drop, and like the egg it takes both reward slots. A week you take feed is a week without a case or a skin. Skipping it isn’t an option: an egg without food never hatches, and a growing bird that goes hungry will leave.
How long the chicken lives once it’s grown, and how it all ends, is covered separately: how long a chicken lives in CS2.
And a real chicken?
A hen sits on her eggs for 21 days, and a young hen starts laying at 18 to 22 weeks. So a CS2 egg hatches three times faster than a real one, and the game gets you to an adult bird roughly two and a half times faster than nature does. For a game pet that’s still a long wait: two months just to find out its color.
