My chickens have had lice. The adult lice are gone but I see eggs all in their feathers around their heads. Yuck. Sevin dust cleared it up but I can't use it again because it makes me get a rash on my arms and legs. So obviously I can't hold my chickens! Going to get frontline and use the few drops method and hope it takes care of the lice eggs too or kills them when they hatch? Or should I try washing that away first? Anyway. Is it frontline plus for cats or dogs? And how many drops per bird? I have seramas who had lice the worst and several others about their size so bantam size and then five standard chickens and 4 half-grown standards.
