Hey there! So I have a silkie hen named Beretta. For months now, she's had a bare back. It's been getting progressively worse since the summer. She randomly started losing feathers on her back this summer and now it's like it is today. I always thought that this happened because other hens were picking on her (which some probably are at night), but none of her feathers have grown back on this bald patch since she lost them. Like, at all. It looks like her feathers just won't even grow back. It's also slowly been getting worse and is happening on her sides and parts of her wings now, too. None of my other chickens have this problem. She doesn't act differently from anyone else. She eats and drinks fine. She enjoys hanging out with everyone else during the day. Does anyone have any idea as to why this is happening? I'm really concerned that she might be sick or that I'm not taking proper care of my chickens.
