Try Nustock for leg mites. It is an ointment made from sulfur and pine tar. Supposed to work wonders. Apply it by rubbing it generously on the shaft of the legs as best you can between and around the feathers. You apply it every couple of days for a week or two and then the scales slough off. (Dont tell anyone but Nustock cured a place I had on my scalp for over 8 years, sorta like a human hot spot like animals and dogs get is the best way to describe it....1 month of daily application and its gone, honest.) I'm using nustock right now to treat my old man rooster in my avatar. I ordered mine. Agrisupply has it in their stores. Tractor supply might. If you need it immediately and cant find it, PM me and I can give you the secret recipeto make it at home. Hope she gets refief soon!
