1. When do chickens start using a roost? Do they have to be trained? Does it need to be a certain size/distance between perches for bantams? 2. What type of feeder/waterer do you prefer in your coop? Do hanging ones work OK? I don't have space for the waterer using nipples. 3. How long should you keep chicks shut up in the coop for them to think it's 'home'? Days? A week? More?
