Ok, it's me again. I think I need a chicken therapist, or my chickens do. They have nicely roosted in their coop until this week, when temps in the 20's and 30's at night. NOW they won't roost in the coop but are staying in their enclosed outdoor run where there is a roost. WHY?????? I tried a couple of nights to move them, but have given up. Do they have the sense to move indoors when they get really cold? Why aren't they liking their coop any more?
