Okay, I read all BUT the last 10 posts (can you say "quitter"?). I'm jumping in.
I have no problems with Stories recommendation in their guide to raising chickens -- except . . . I don't really want to prime my coop to burn down with kerosene. I don't like the smell either. But, other than that, fine.
I don't think the bathing, toothbrush scrub, Nu-"stuff" with pine tar, etc., etc., is a bad idea. However, this is what I do (ever since a friend "gifted me" wit four rhodies with leg mites):
I prophylactically treat all my birds and coop. I keep a jar of vaseline in the coop. (Which is just as flammable as kerosene, btw.
) and I grease the legs of roosting birds anytime I'm in there at night. I also apply vaseline to their roosts/perches. I will apply vaseline to the nesting boxes when I clean out the coop. Once or twice per year I will completely empty out the house and spray with permethrin. I do this in the summer when the birds spend the least amount of time in the coop.
I have not had any mite problems arise with my vaseline prevention. It's cheap, it's easy.
