So am I the only one having mite problems this winter? I have read where it can be an immunity issue.....I have changed their minerals, they are copper bolused every 6 months, they get good hay, I keep their pen very clean....clean up every day, although with being winter and sooooo cold I have not cleaned their bedding completly out, but treat it with powder and I have treated the boys with Ivermec pour-on, dusted them, VetRX.....I finally went to the vets today and picked up Permectin II, what he suggested.....The only thing left is injecting with Ivermectin.....I just hate giving shots, but will do what ever it takes. I have researched and read everything I can and I know it's mites.....I even thought about zinc def and tried that. Any help or advice would be great! I plan on shearing them as soon as warm weather gets here.
