ok winter is coming on i live in alabama. my 3 hens have slept on the top of their coop. no big deal while it was warm and hot out. now i am trying to break them from that and put them inside the coop. rosey and daisey do good i put them in and they stay in (except last night rosey didnt want to stay in) so i let them sleep on top since it wasnt real cold. it is supposed to be getting down in the 4o's this next week some. my question is will they get inside the coop themselves if its real cold or will i have to continue to train them to be inside it? my husband says they know when its too cold to sleep up there and they will get inside it when they get cold. i say i dont know and dont think so because they have been used to sleeping on top of it. so what does anyone think about it????
