Might be a silly question, but my girls like to cuddle on the floor of the coop. sometimes they roost in the run and even in the coop - but it seams like most nights they are on the floor in a group. its not yet that cold here so i don't think it because they are cold. so why must chickens roost? I have had people tell me "its what they are suppose to do" I don't know if i agree. My girls are happy and healthy. I figure if they needed to roost - they would. what do you think?
