I am trying to figure out what would be the best for the dust bath for the chickens. I read some of the posts, but what is DE?
DE is diatomaceous earth, the ground-up skeletons of microscopic ocean organisms. You must purchase "food grade" DE. NEVER EVER EVER use pool grade DE, which has been heat and chemically treated and is highly toxic for everyone and everything.
I had a hen get ill and took her in to the vet (and she got well). I also took a fecal sample. The results were that she has no parasites whatsoever, inside or on her skin, and due to the nature of a bird flock, if the one hen is parasite free, the other hens are assumed to also be parasite free. Their pine-shavings layer on the floor of the coop has DE mixed in, and I mix DE in with the their mash. So they dust bathe in it, and get it internally. So far it is working for us.
DE is excellent as a nutritional supplement for humans and all the rest of any animals you may keep.
