I was checking the health of my bantams like I do about every week by picking up each one and inspecting their feet and faces and I decided to brush up their feathers and they have little tan bugs on them, I am assuming chicken lice? maybe mites? What do I do? PS I know my coop is clean and they are on a movable tractor that gets moved every day, I got them a month or so ago from people who had about 200 bantams in a small dirty cage, I bought 22 and sold several ( I will be contacting the people who bought them to tell them that they need whatever treatment you all say I need ) I just wanted to make it clear that I take great care of my chickens, unfortunately the last people didnt. Fortunately they are kept separate from my other chickens and I will be checking them today to make sure they dont have it too.
