I've been reading this board for quite some time now and have gotten some really helpful information. Thanks! This is my first attempt at keeping chicken and with all the info I have found on this site it has gone off without a hitch up to this point. Now I'm stumped. We just finished the coop and moved the girls (23) into it. We have a great roost in there for them and they won't use it. Well.......they sit on it during the day but when it comes time to sleep they pile into a heap in the corner. Is this common?
