So, I had the great idea to put pavers under the coop and cover them with a nice layer of sand. The attached covered run has just dirt. So, far I have noticed that the sand area is a bit smellier than the rest of the run. How do I go about cleaning it/maintaining it? I guess I didn't think this part through. If it was in the open, rain would wash the poo away and leave me with cleanish sand, but since it's under the coop, that's not going to happen. I really don't want to have to crawl under there and pull out 4x6 worth of pavers, but may end up having to do that if the smell gets worse. Any ideas for a better alternative for litter under there?
