Hi, I just noticed one of my year old white orpingtons has horrid looking raised scales on her feet. I've soaked her feet in epsom saltwater and applied VetRX oil, getting it deep under the scales. I did this three days ago and again just now. Is it possible this is something other than scaly let mites, like some genetic anomaly?? The other 11 chickens look great, although I've treated them too. I've gotten great experienced advice from all of you in the past...thankyou!
