So, I have 12 chickens in all. 11 are pullets, and 1 is Cockerel. They're all about 2 months old, and they are living in a pen outside. We are starting to work on a chicken coop, we have an idea of where the nesting boxes will be, but I have three questions. 1) What should my family build that would be comfortable for the Cockerel to sleep in/on? 2) And what would be some good things to use for nesting boxes. (I've seen boxes and crates used as nesting boxes), is there anything else that could be used? 3) Will the pullets have a sense of which nesting box is theirs as they grow familiar with the coop?
