Chicken has missing feathers and bright red skin

[Poultry finder]

I had a few hens with missing back feathers and bright red areas on thier backs i took roosters out for about 5 months now and dusted the hens and wormed them. All but one have grown thier feathers back but my speckled Sussex hen has been dusted multiple times she moltted earlier in the spring so she should have her feathers back but her back is still bright red and featherless does anybody know what this is and how to treat it?

I would suspect mites but you said you dusted. Any chance the other hens are pecking her and keeping it red and irritated?

It is probably feather picking from one or more of the others. They can develop the habit of picking feathers from boredom, over crowding, and a lack of enough protein in the diet. Sometimes I also feel it could be from a lack of certain minerals in their diets also. You need to check her for signs of lice, mites, or their eggs. Then make sure they get outside to roam daily, are getting a balanced 16-20% protein layer feed, and try placing some distractions, such as a cabbage or flock block to peck on. Even with doing everything perfectly, you may occasionally have some feather picking. Nustock cream, a bad tasting antifungal cream from feedstores, can be helpful when applied to red bare skin.

I have kept ber seperated from all other chickens in a big outside area with a view of the other chickens i put protien block before and different types of protien filled feeds mixed together and i have put many different creams and things that would taste bad on her but there are still no pin feathers and the skin is still bright red have i even tried to put a sweater on her but to no avail

I would see if she is pulling out her own feathers then. Also, are you sure that she molted in spring? My first chickens included several who had bare backs the first year, and they remained bare until their first molt at about18 months old.
