hello everyone. I just discovered that my hens have mites, gross. My problem is how to treat. My vet is looking into it. But I didn't know what I could use to clean their coop with. the vet was worried about using harsh chemicals. The coop of course is made out of wood. I also don't know how to prevent any further infestation? Ihave a whole woods full of chipmunks, etc that get into the coop (I'm sure those little critters are full with mites and who knows what else). Thanks for any suggestions you might have!
