I heard that dipping hens feet in vegatable oil can get rid of leg mites. I put a tub down in their doorway where they pass through to get outside then it would help to kill any mites they might have. At the moment they just seem to drink it. I have 2 questions: 1) Will it do them any harm drinking it as they seem to like it and drinking quite a lot? 2) Has anyone got any quick ideas of how i can treat all my birds for scaley leg mites that is quick?
