I just discovered that all my flock of 30 chickens have lice\mites, and i was going to use sevin dust 5%, but then I reaserched and i got the heebie jeebies!! (search "sevin dust cancer" and you will get NIGHTMARES) , I had heard of using wood ash and rubbing it on them, has anyone had any luck with this method?? I would like to avoid usign DE if at all possible, as I am not a fan. oh, and if it helps, I have only seen poultry lice on them, but a few of the chickens match the list of symptoms for red mites word-for-word. thankyou!
