Key Strategy Insights
- Sergeant Hen is the Thunder route gateway — 100% Thunder Egg lay chance, the highest in the game.
- Viking Chicken is a dual-layer — lays both Scratch and Thunder Eggs, unlocking two key branches early.
- Agent Cluck is the rarest Arena pull (2%) but lays Fortune Egg (45%) — never sell before using it for the Fortune branch.
- Egg rarity tags are inferred from the laying chicken's rarity — the in-game chart assigns rarities to chickens, not eggs.
- Fusion trait transfer can move egg-laying traits between chickens (e.g. Thunder Egg trait to a combat chicken).
