I have built my chickens the Taj Mahal of chicken coops. It is clean, with fresh pine shavings bedding and lots of food inside. My chickens suddenly stopped going in it to roost. I still find my eggs in the nesting box so they are going in to lay. But at night they prefer hunkering down in the dirt or roosting up on top of the fence (I have surrounded the coop with a dog kennel to keep them safe from my dogs). I have forced them into the coop at night and they make such a fuss about coming outside that I let them out. Except for this one weird behavior they seem happy and healthy. They are plain white chickens that lay brown eggs. I don't know their breed. I wanted 5 hens from my friends. They gave me young pullets which 2 turned out to be roosters, the Colonel and Popeye. They seem to like me and come to the door of the kennel and even when I don't have food they follow me around as I do my work in the chicken yard Does anybody have any ideas what could be wrong with my coop/chickens/me? I worry about them as winter approaches.
