Answer 1

Chickens are domesticated versions of Red Junglefowl (technically still the same species!) native to SE Asia. Bamboo there flowers/seeds on a multi-year cycle, so every several years the ground is COVERED with seed. These birds have adapted to go absolutely nuts when this happens, eating a ton and making/laying tons of eggs.

Domestic chickens have this “switched on” all the time, because we can feed them lots of food all the time.
