I have a 22 week orpington that appeared with a wet area on her back, between her wings. On inspection, her skin in this area was raw and red and wet, like the skin under a scab that came off prematurely. We isolated her and applied neosporin. She doesn't have any other symptoms and is eating OK. Her feathers have dryed out and it is now only evident if you pull back the feathers to look at the skin. Any idea what this is and can I return her to the others?
