I am having the worst time trying to treat scaly leg mites. Last year I noticed that my rooster had some raised scales that were probably leg mites. So for several times, once a week, hubby and I dipped all the chicken legs in some old olive oil. Then we figured it was taken care of and he just needed to heal up. Well, his legs never looked any better. Next, we tried again with the same thing, except we dipped in olive oil and then added pyrethrin dust to their legs. Waited a while for legs to heal, but still there was no change. Then we treated all the chickens with ivermectin in the fall. They passed some roundworms so I know the ivermectin treatment worked for something at least, but there still has not been any change in the legs. Now I have been treating them daily with vaseline for the past two weeks, but still no change except that my chickens are greasy and upset with me. Haha. How long do I need to do this? Is this normal for it to be so hard to get rid of? Does my rooster just have ugly legs naturally?? Thanks for any advice!
