I tried DL last winter, and found that it did not compost well at all, even with the addition of some compost and soil from my garden. I think key to success is having the coop sitting on bare soil. I'd love to hear from someone who is successfully doing DL... not just deep litter, but deep composting litter in a coop with wood floor. But, hope springs eternal! Am having an other go at it this season with some shavings, and lots and lots of leaves. I regularly toss some scratch under the perch. Even if it does not compost, the girls will have fun flipping through it for the scratch, and when I do eventually toss it out into the run, it'll be well on the way to becoming good compost. My run has a gentle slope. I'm doing DL there as well. I dump my bags of leaves in the front end of the run, and the girls pick through them. Eventually, due to the slope and their attention, the leaves end up migrating to the lower end of the run, where there is also a clean out door under the perch end of the coop. So, there's some nice layering going on at the lower end. In the spring, I'll cut an other door into the run at the lower end. Perfect for hauling WB loads of finished compost out for the garden!
