What to know
- The 404 Chick comes from Cursed Eggs, so you need to work through several chicken and egg tiers first.
- Start with the Classic Rooster to farm Nest Eggs and hatch a Cosmo Brat.
- Cosmo Brat leads to Scratch Eggs, which can give you the NPC Chick, while NPC Chick is used to farm Cursed Eggs.
- Stone Face is the best final farming step, as a leveled-up Stone Face can guarantee a Cursed Egg roughly every minute.
If you’re trying to unlock the secret 404 Chick in Grow a Chicken Fighter, you cannot simply start farming its egg type immediately. The game uses a progression chain where one chicken helps you obtain the eggs needed to unlock the next chicken. Once you understand that chain, the process becomes much more straightforward.
| Stage | Chicken | Egg produced | Goal |
|---|---|---|---|
| 1 | Classic Rooster | Nest Egg | Hatch Cosmo Brat |
| 2 | Cosmo Brat | Scratch Egg | Hatch NPC Chick |
| 3 | NPC Chick | Cursed Egg | Hatch Stone Face |
| 4 | Stone Face | Cursed Egg | Farm for 404 Chick |
| 5 | — | Cursed Egg | Hatch secret 404 Chick |
The most important part of this method is knowing when to replace your current chicken. You start with the Classic Rooster, but each successful hatch eventually gives you a chicken that is better suited to producing the next type of egg.
How to start the egg progression with Classic Rooster
Your first objective is to obtain Nest Eggs.

Deploy the Classic Rooster into your coop and allow it to produce eggs while you play or AFK. You will want to collect a reasonable number of Nest Eggs rather than immediately stopping after getting only a few.
The purpose of this first stage is not to directly obtain the 404 Chick. Instead, you are using Nest Eggs to work toward Cosmo Brat.
How to get the secret 404 Chick in Grow a Chicken Fighter
The 404 Chick is obtained by working through a specific chain of chickens and eggs. You need to progress from Nest Eggs to Scratch Eggs, then Cursed Eggs before you can efficiently farm the secret chicken.
Step 1 — Get Nest Eggs and hatch Cosmo Brat
Deploy the Classic Rooster into your coop and let it work while you AFK. The Classic Rooster can produce Nest Eggs, which you need to collect in large quantities.
Keep hatching Nest Eggs until you obtain Cosmo Brat, an Uncommon chicken.

Cosmo Brat is important because it has a 100% chance to lay Scratch Eggs, making it the next step in the farming chain.
Step 2 — Farm Scratch Eggs with Cosmo Brat
Once you have Cosmo Brat, deploy it into your coop and AFK again.
Use this setup to collect a large number of Scratch Eggs. Keep opening Scratch Eggs until you hatch an NPC Chick.

You need the NPC Chick to progress to the next egg type.
Step 3 — Use NPC Chick to get Cursed Eggs
Deploy the NPC Chick into your coop.

NPC Chick has an 80% chance to drop Cursed Eggs, so let it farm while you AFK and build up a decent supply.
Once you have enough Cursed Eggs, start hatching them until you obtain Stone Face.

Step 4 — Upgrade to guaranteed Cursed Egg farming
After getting Stone Face, deploy it into your coop.
A leveled-up Stone Face can guarantee a Cursed Egg roughly every minute, making it significantly more efficient than relying on the NPC Chick’s 80% drop rate.
This is the farming setup you want if you’re trying to hatch the secret 404 Chick efficiently.
Step 5 — AFK farm Cursed Eggs

Leave your Stone Face in the coop and AFK farm for an extended period.
Because the leveled-up Stone Face provides a guaranteed Cursed Egg roughly every minute, you can build up hundreds of Cursed Eggs without constantly having to collect and replace chickens.
Step 6 — Hatch Cursed Eggs for the 404 Chick
Once you’ve accumulated a large stack of Cursed Eggs, start opening them.
The secret 404 Chick can be obtained from Cursed Eggs, so the main goal is simply to keep hatching them until the secret chicken appears.

The complete progression is:
Classic Rooster → Nest Eggs → Cosmo Brat → Scratch Eggs → NPC Chick → Cursed Eggs → Stone Face → 404 Chick
The important trick is to use each newly obtained chicken to farm the next egg type rather than trying to jump directly to the 404 Chick. Stone Face is the key endgame farming chicken because its leveled-up Cursed Egg production gives you a much more reliable way to mass-hatch Cursed Eggs.
404 Chick farming rewards
| Stage | Reward |
|---|---|
| Nest Egg farming | Cosmo Brat |
| Scratch Egg farming | NPC Chick |
| Cursed Egg farming | Stone Face |
| Mass Cursed Egg hatching | Secret 404 Chick |
How to make the 404 Chick grind more efficient
The biggest mistake you can make is trying to rush straight toward Cursed Eggs without building the correct farming chain.
Each chicken has a specific role in the process. Classic Rooster gets you started with Nest Eggs, Cosmo Brat moves you into Scratch Eggs, and NPC Chick introduces Cursed Eggs. Once you obtain Stone Face, however, you should focus on upgrading and using it rather than continuing to rely on NPC Chick.
It is also worth collecting eggs in batches. Opening a single egg every time you receive one makes the process feel slower and forces you to constantly interrupt your farming. Building a stockpile lets you perform larger hatch sessions and makes it easier to see your progression toward the next chicken.
Most importantly, don’t treat Stone Face as just another hatch. Stone Face is the chicken that turns the final part of the 404 Chick hunt into a repeatable farming loop.
