When my girls are ready to go to the coop full time I'm supposed to keep them in there for 3-4 days. But is that in the roost area only or the whole tractor. They go in there during the day but I bring them in the house at night. They don't seem to want to go to the upper part of the tractor and when I got home after dark last night they were sleeping in the grass. So... Just lock them in the roost for a few days or not?
