One of our hens began hanging out in one of the nest boxes a couple of days ago. We thought she had gone broody, until today when we pulled her out of the box. All of the feathers on her chest are gone. The rest of her feathers look normal. The only other thing we noticed is that she's got several small scabby looking spots on her face around her beak. I wonder if the other girls have been picking on her and pecking her face while she's sitting in the box, but this doesn't explain her missing feathers. If the others were picking on her, wouldn't she be missing feathers on the outer parts of her body, and not the underside? Surely she's not molting in January. We haven't noticed lots of feathers anywhere. It's well below freezing here, so we think she's staying in the box to keep herself warm. Does anybody know what could be happening with her? I don't want her to freeze, because she doesn't have enough protection.
