Update: Went out this morning while it was still dark to look for those nasty mites - I FOUND NOTHING. Rather, I SAW nothing. When we cleaned the coop a couple weeks ago I sprayed everything down with bleach at 200 ppm. My question is if there are still mites living in there, would anyone recommend spraying the coop with Neem Oil? It's sold as a miticide at Home Depot and would be readily available for me. I think I might consult my vet about Frontline Plus for use on our chickens, seeing how we use it for the dog anyways.
Additional question: Let's say the mites/lice/whatever were killed off, how long would it be before I see improvement in the chicken feathers? Basically, I want to know if what I am doing is working without allowing things to get worse. Thoughts?
