A few months back I had a problem with one of my Buff Orps sleeping on the roost outside in the run instead of inside the coop. We took the roost down after I had to pick her up and put her on the roost in the coop at night for 3 days. Our winter has been so bitter cold and snowy that I didn't want to find her frozen to the roost in the morning. She finially got the hang of going back in at night. I would check her and she would be sleeping on the floor. One was in the nesting box and another was on the roost at the other end of the coop. Plenty of room for her, but noooooo, she still snuggled on the floor. At least she was inside. A few weeks back we put the roost back up and she is now, once again is sleeping outside. I cannot move her every night, so we have been keeping the little door on the coop open so if she changes her mind she can go in. The coop is inside the run, and all is covered with plastic sheeting to protect the girls from rain, snow, wind. The other 2 never hesitate to go in side. We had previously removed 2 White Rocks that were very agressive and brutal to the buffs. Margo is the head cluck now that the two nasty birds are gone. She is the one who insists on sleeping outside! Any thoughts?:/
