The Chickenpedia is the in-game encyclopaedia that contains images, size information, statistics and brief (usually humorous) descriptions about the chickens. Entries are unlocked as each one is discovered. There is an achievement for completing the Chickenpedia.
The arrows below show how the Chickens mutate, and which level they are found in.
