So they have been in the coop for about 1 1/2 weeks now and they haven't gone back into their coop yet. Its not a huge deal i just worry right now cuz its cold at night. I've been manually putting them up top with the heat lamp but i'm hoping they get the idea soon. I was wondering how long it took your chickens to want to sleep in their coop at night? Here is a pic of mine to give you an idea.
