I have a chicken who has scaly leg mites. I've been doing Nu Stock since Thanksgiving and still having issues. Guy @ the feed store told me he had a fungal infection so I have not sprayed or done anything to treat house or coop. Possibly why we are still having issues. He's the only one I see w/ a problem. He is a feather leg, but I also have 4 other feather legs. I can't see the mites singling him out. Anyway I did change 90 % of shavings & I sprinkled DE in house last wknd just to clean. I starting research leg mites, and this guy posted he sprays his chickens head to toe every 3 months w/ Adams flea & tick w/ IGR to prevent both leg & body mites. Is this safe to use on chickens? Thanks
