I can't tell if she is getting some more feather hence normal or if she is being picked on. I haven't noticed anyone picking on her and she is kinda fiesty. This is pictures. There is just the smallest amount of scabbing. There is new feathers coming in. Her skin seems very yellow. 22 week old barnie (suspect part ameracauna) eating fine, drinking fine, running around, some panting (but hot here). No conditions I know of to make the spot. She has had it for 3 to 4 days maybe. Don't know if she is laying yet. I have two that could be green egglayers, she's one. And I'm getting one green egg a day or so. (50% it is her) Edited to add hopefully useful information.
