I've been given 2 new girls and they have leg mites. We have cleaned them and treated with oil just wondering how long it takes for them to be gone completely. They are in a dog carrier at the moment since the new coop isn't fully built yet and have them in my bathroom so they can get out and stretch their legs. Their combs are not particularly bright so have given them some yogurt and put Rosemary leaves in the straw is there anything else I can do to get them healthy? I have had my other girls about 6 months so fairly new Chicken lover here.
