Hello! I have five 5-month old Faverolles who are nearing the egg-laying stage. However, they insist on sleeping in one of the nest boxes. All five of them. I've tried everything I can, and I've resorted to stuffing the box with a burlap bag. Hopefully that will work. I've also noticed that whenever they don't sleep in the boxes, they sleep on the floor of the coop. I have a perfectly good roost that they never seem to use! Any suggestions?
