Animal products food production for the larger colony

[The Man with No Name]

Speaking from experience, I tried an egg farm from turkeys, they don't produce fast enough to be worth it for eggs.

Yeah, I've noticed that in my game.

As has been mentioned, chickens are the best in A16. Slaughter all males (except for one) when they reach adulthood. Keep as many females as you can handle, slaughter the rest.
Chickens can get out of hand fast. So beware.

True, chicken are the only animal that is really worth to farm (indoor)

Iganas, tukeys and cobra might alose be effective, but they reproduce slowly, you need to start with a lot of female to have  descent imput.
Iagana and cobra eat corpses too, that can help if you don't have any other animal to clean dead raiders and thoses 30 dead chick ( baby untrained dogs or bears can eat thats too if no other food access)

But still chicken are the best from far, if you get to too much, throw a grenade
