Grow a Chicken Fighter All Eggs: Hatch Odds, Layers & Routes
Eggs in Grow a Chicken Fighter are not bought in a shop — every egg comes from a chicken that lays it, a code, or an event. That makes the game one long egg chain: the starter Nest Egg hatches Cosmo Brat, Cosmo Brat lays Scratch Eggs, and Scratch splits into seven branches that lead to Haunt (Doll Hen, Reaper Rooster), Royal (Radiant Fenghuang, Phoenix Hen), Cursed (404 Chick) and the rest. Below is every egg with its layers, its full hatch pool and the chicken worth chasing in it. Percentages are the in-game Egg Index values (snapshot Aug 12–14, 2026) cross-checked against gameplay footage. Ranked version: egg tier list.

Egg FAQ
Do eggs cost Cash or Robux? No source shows an egg price or an egg shop — eggs are laid, redeemed from codes, or won in events; Robux only buys boosts and passes.
Which egg should I open first? Scratch — it is the gateway to every branch. Then pick a branch by the skill you want: Haunt for Voodoo, Royal for Cycle of Ash / Rebirth, Cursed for the 404 Chick. See the beginner guide.
