I don't have a dirt floor and I use the DLM - I have a wood floor - I use DE in it, add some shavings and mix it. Every morning I mix, and in the evening. Weekends I scoop out the poop, as much as I can, then add more shavings. Works for me. A few times a year, usually when rainy season hits, I empty out the whole coop and start over. The trick is not to add too much shavings, as the ammonia smell will overpower you and cause breathing problems for the chickens.
