I have dusted for mites/lice numerous times because the hens are full of broken feathers.. Then I switched to using the 10% permerthren spray. It sticks better to the birds, and takes care of mites in the roosts. The dust doesn't do that. Only time will tell, as in when the hens molt again, if they really had mites/lice or not. Their feathers are in bad shape and I am waiting till they grow new ones.
