Is what I've been doing since I got the chickens. About 8" of shavings, give or take, and added to as needed. Then I was reading one of the books I bought before finding this site and it mentioned you can't use DLM unless you have a dirt floor. Won't compost. I guess I can see that, but we seem to be doing fine so far. Coop is dry, I turn over the top layer and scoop up some poop, but mostly it just dries up and disappears. Also use DE. Anyone else using DLM without dirt floors, or am I the only idiot?
