So we finally got our "Human Consumption" Grade DE. And we have been using it in our coop and the chicks dusting areas. My question is this: It is not healthy to inhale the flying dust from the DE. Is that true for just humans or animals too? When we have it in the coop and the chickens are flapping around the DE continually scatters into the air. Is this OK for the chickens? Very confused here...hope someone can clear this up...No pun!
