Hi, we're new here and need some expertise! We have no problem getting our chickens into our coop in the evening, but they don't seem to want to sleep in the coop. Instead, all six of them pile up in the open doorway between their coop and their run. They've done this ever since we moved them from the tractor into the coop about 6 weeks ago. We're worried that there is something in the coop they don't like that's causing them to not want to sleep far inside. The coop is plenty big for all of them. We had roasters in there before and they liked it just fine. After the roasters went away we cleaned it thoroughly and moved the layers in. Mites? Something else? Any ideas? Many thanks.
