I'm having a small leg mite crisis. It took awhile to get the chickens cleared up, but the guineas appear to have them and have passed them back to the chickens. I can't get anywhere near the guineas to treat them and there's no way to ensure they stay out of the chicken run. I try to run them out when I see them in there, but guineas do what guineas want. They roost way too high for me to reach them. How do I treat these wild things?
