For deep litter on dirt, how does rat control go? In a way, this sounds like the best method for us, but I'm sure the rats would find a way in in no time, even with hardware cloth, if there was any wood at all near ground level. Is the base of the wall concrete block? How high up is the chickens' door, and the door for people to get in (for cleaning, etc.).
Our current coop has plywood laid loosely on hardware cloth about 16" off the ground, and the rats probably ate about $100 worth of organic feed last summer before we finally poisoned them. They mostly came in up the chicken ramp, but one of them was gnawing a hole in the OSB back door the other day. They are mostly under control at the moment (the hole-chewer has not re-appeared) but I'd rather not resort to poisoning again.
I mean, I think the plywood floor, 18-24" up, is pretty good (and reading this, I might see if there's some scrap linoleum in the neighborhood to add) but I am sure deep litter on dirt would compost better, which would be great for us if it didn't get riddled with rodents.
Thoughts?
