Need major help. I took my girl, scuttlebutt, to the vet because she was inactive and looked I'll. Dr.indicated that she had a severe mite infestation and some small maggots. The Dr. anesthetized her, thoroughly cleaned her, and treated her. The Dr. just called and said her bloodwork was excellent, overall health looked good, just those darn mites. Although she will continue to treat her, I need to know the best safe remedy to put on her, (spray? Topical?), and liquid solution to clean and disinfect the yard. I have 2 other hens, so I will be treating them as well. My girls sleep in an old bedroom at night and free range throughout the day. Please help. My girls mean the world to me. Thanks.
