I’ve got a 1.5 year old Buff Orpington. Seems totally fine and healthy except for her feathers on her belly. She is not broody, though since I got her two months ago she sleeps on the coop floor instead of the roosts. No matter how many times I put her on the roost, she ends up on the floor. Pics seem to show new feathers growing in? No sign of mites that I can see. Thoughts? (I’m a newbie with four hens and really appreciate guidance! Just want to do right by these ladies)
