My other post messed up. I think I overloaded with pics. Cochin of unknown age. Harmony came to us a cpl months ago in poor condition. She has never had feathers from chin to vent. Now she has this thick flack pealing skin. It's getting matted into the feathers. Evereyone just went through treatment for scaly leg. They came to me this was and it spread! The coop is spotless as is the run. They free range during the day. I noticed during treatment she was extra flaky. Her feathers have turned from blue to almost brown. She needs a good moult. The feather are not trying to grow back. I sat for an hour removing skin. On bald spots it peeled like sunburn, but dry, feathered aread were built up and nasty. Could she not be preening? Skin disorder? Could she have had mites before the ivermectin tx? please help me help her. they deserve happyness! She is the only one like this. I do have another one of the cochns that doesn't have feathers in this same area, but no skin issues. I thought she was broody for too long? I gave her a good scrub with selson blue as it's all I could think of. She's running around with the others now. Looks better. Some pics: After picking the flakes off. See the flake. Under. Front. Current color. Color before. TIA!!
