So first of all, my chickens have lice (Ugh!). I bought some DE (food grade) to sprinkle in their dust bathing areas, however I was wondering if there was another way to apply it to chickens. The instructions say you can make a white wash out of it to apply to a coop, but could I just wash the chickens in it as well to get rid of the lice? Or would it work to use it straight as a powder on the bird? I really need to rid my flock of lice. I'll be hatching some eggs in a few weeks, and I don't want the chicks to accidentally get infested. I've had chicks die from lice infestation. Also, poultry are not allowed to go to fair if they have lice. Any other ways you can suggest to help me rid my flock of these pests? I have the manna pro poultry protector spray, however it oinly says to use as a preventative. I can't find anywhere where anyone says it actualky works to treat the lice. Just thinking of the possibilities. Plus my chickens need baths anyways after the muddy season. Thanks for any help in advance!
