HELP one if my babies is going bald from the "bottom up"! My 5 hens are almost a year old. We live outside of Portland, Oregon. Today I found that one of my hens has no feathers from under her butt clear up to her breast bone. The skin has little scabs nearer to her butt and it almost looks like the skin has peeled. There is no rooster and we have always thought that this hen does not lay eggs. She's the only one I have never caught on a nest. So how do I proceed? Treat for mites? Wash her and apply antibiotic salve?? Should I even get her wet? A couple of the other girls are missing a couple of feathers here and there which I thought would be molting, but nothing extreme, no baldness like this one. Poor Donna Jean, can someone help her?
