I have a flock of bantams that like to sleep up in the rafters of my carport. Since it's down in the 20's overnight, I've been going out after dark, collecting them and putting them inside the coop with the 2 older big girls. BUT, without fail, when I leave for work in the morning (still dark), they've moved back to the carport rafters. I really didn't think they'd move once it was dark, but they do. Any thoughts on forcing them to stay in the big coop? (The Carport and the chicken coop, a shed, are all wired in together, sides and roof. This is not where I park my car, but a carport that covers my wellhouse and now houses the flock.)
