I've dealt with lice (clear bugs) on my roo but now my girls and probably my roo have lil bitty black bugs and I'm sure they're mites. I have 23 chickens!!! How can I dust 23 chickens with DE????? I have to clean out the hen house. If I clean out the hen house and dust it with DE and add DE to the feed will that kill the mites??? I seriously doubt I can dust 23 chickens!!! I HATE BUGGIES!!!!!
