OK I've read that people can just fly through cleaning sand in there brooders,coops,runs ext. It takes me a good hour to do mine. I find i have to sift right to the bottom and remove wet spots and droppings, I've tried raking it but it didn't seem to get everything. My brooder is approximately 100 sq feet. I'm a fast thorough worker and I've even made some pretty efficient tools to clean . I don't know how you can pull it off. I'm thinking i should reduce the amount of sand to around two inches to at least speed it up some what. Am I being way to annal or should i drink a couple red bulls before i start ?? Any ideas would be appreciated thanks.
