We live in Arizona and right now we are in the monsoon season. We are getting anywhere from a half an inch to three quarters of an inch a day to every other day and our chicken runs are a mess. What is the best way to keep them dry? Is sand or pea gravel good for drainage and keeping things dry? We also need something to help keep the flies down, they are horrid right now. I have heard and read about a product to keep the smell down but I have not seen it in this area and right now it is bad. I can't imagine that their feet being wet a lot of the time is good on their feet, please help us dry out their feet.
