These might be silly questions, but we are very VERY new to raising chickens and our little chicks are just about old enough for their coop. We are converting a shed into a coop for them. We've built nesting boxes for them, but I'm a little confused on exactly what they need in a coop. When I looked at the nesting box designs I read that you don't want them sleeping in the nesting box. Does that mean that We need to provide roosting boxes as well as nesting boxes? How do the chickens know the difference? I was planning on putting straw down on the floor of the coop and wood shavings inside the nesting boxes. Help? Thanks!
