She’s approx 18 months old, we got her mid April, with a sore on each wing she kept picking at, we bathed it in Epsom salts and although looked dryer they wouldn’t go as she continued to pick, two little patches. She also had that “dirty bum” which cleanered up with apple cider vinegar.
Shes been with my other 2 girls now for about a month, she starting losing feathers, around her comb. I treated all 3 with mite power (treats lots of different things too) she then started loosing lots of feathers I thought it was a moult as she stopped laying and we are going into winter. But she’s lost so many feathers and left with bold patches which are now turning almost black! She won’t let me near her but it appears all her skin is turning black, she’s been like this for over a week now and today her comb has black patches. The other 2 hens are completely fine! She is fine in herself, eating, drinking, just looks awful and doesn’t like being touched.
