We have a permanent coop and run. In the coop, I put down straw and pine shavings and clean it out weekly, no problems there. In the run, we've put down a couple layers - probably 2-3 inches thick - of river rock pebbles over the dirt. But the poop builds up fairly quickly, to the point where you can barely tell there are rocks there. The run has a roof, so water doesn't get in there to wash it away ... should I hose it down? Over the weekend I took a pitch fork and tried to 'turn' it over a bit and get the rocks back to the top and poop into the ground... not sure how effective it was though! Any recommendations for a better/different floor for the run? Here it is looking good after more rocks at the end of summer... but now it's a poopy mess!
