How long have you raised chickens ? It is natural that chickens poop where they walk, and eat. They pass parasites that way which they pick up from earthworms, which are natural for them to eat. What is not natural, is that we confine them to coops where they are constantly being exposed to more feces, and more parasites. DE is not a wormer. It is ineffective the minute is is wet, as in a chicken's gut. Take a sample of poop to any vet for a fecal check, and you will be horrified.I use DE in their feed, it's all natural.
