I can't imagine nor would I ever try this in a regular type closed in coop that is not on dirt flooring.
I don't understand how that would work.
My coop has a wood floor coated with rubber roof coating. Every spring I clean the coop, put a small layer of pine shavings. Then every couple of weeks I add a layer of grass clippings, then leaves, then some straw (two week or so interval). I switch it up each time but use more grass and leaves then straw. By the beginning of winter it is about 12 inches deep and the bottom is broken down really well. I spread this over my garden and let it sit for the winter. Then I start the same process over again. Works out perfectly fine. No smell and every time I add a new layer the hens really get everything stirred up and broken down.
By definition it might not be considered a true deep litter method but I have done this for years and love only have to scoop it all out twice a year, and my garden loves it too.
