My flock free ranges during the day, so there's not so much to clean. There are four coops, all with dirt floors. I use the deep layer method - sprinkle sweet PDS first, then DE, then lots of medium/fine mixed pine shavings. The boxes all get fresh hay whenever they need it, usually once weekly. Any surface that is poopy gets scraped daily and I do pick out soiled hay daily in the boxes. Every weekend I rake the coops, really just stirring things up a bit. I will add more DE or sweet PDS if needed and sometimes more shavings. Every now and then I will shovel down to packed dirt and start again, but I do that only a couple of times a year. Whatever gets shoveled gets spread around the back yard which is really making the grass (and weeds) grow well.
Before I tried the deep litter method, the pens stank even with a weekly shovel-out cleaning. Now with the pine and sweet PDS, nothing smells plus the DE keeps the flys to a minimum.
