A few weeks ago I noticed Esmeralda's feathers on back started looking like this. None of the other chickens have any issues with their feathers and it doesn't seem to bother her. I bought a saddle for her, will this help? I haven't noticed Mercy (the Silver Laced Wyandotte roo) showing her too much attention but yesterday I DID notice he gave her a peck on her back. I looked for mites but haven't noticed any. And, just to complicate matters further, I notice this morning that her bottom, below her vent, is looking a bit featherless. Is this feather picking? Aaaah! I want to help my poor sweet girl.
