My babies are still very little and only going out in the large run a couple hours a day, but already there's flies all over the poop in the grassy run. How do I remedy this? Can I "flour" the grass with DE? Should I? Also going to be getting some Sweet PDZ for inside the coop tomorrow but don't know what to do about the grassy run when it's warm and not rainy to dilute the poop into the grass. Thanks all!
