I just read permethrin is good for treating lice on chickens and wanted to know if I need to get a certain brand or what percentage concentrate I need to get? I suspect my chickens have lice, I’ve seen some in the nesting boxes and I see them grooming a lot. Also wanted to make sure it’s safe to treat their pen while they are still in there or do I need to move them? How long should I treat them with it?
