I just got my chickens on sunday. The first night they slept on the floor of the coop and I let it go by because i thought it was because they just moved into a new home. Then they noticed the nest boxes. They are now sleeping in them. They keep some for sleeping and some for laying. I have a roost but they don't even got on it. I want to know if sleeping in nest boxes are bad for my chickens that they are not roosting or should I let them do it and has this happened to anyone else?
