I totally clean my coop/run out about once a month but I am always removing dirty & adding clean straw to the more icky parts of the run about once a week, more if it's been really rainy. The ducks make quite a mess right around the pool though so that's kind of a must. I turn the bedding everyday though since I am out there checking on everyone anyway. I have a large area where our pigs used to live that I can dump the bedding in to compost. When that is finally filled in, we have their weirdo 'sink hole' spot on our property that's always been pretty mucky and just kinda eats stuff up... i don't know how much tree branch, plant, shavings, and other compost stuff we have put in there!!!
