I have started my building my coop hope to have it finished this weekend. Im putting it in my back yard so we can watch our chicks from the porch. My problem is water. My land is very flat (all 5 acres) and nothing but clay so water just stands if we get a significant amount of rain. Any ideas on how to make a run stay dry. Thought about some kind creek gravel and a creek type sand built up on top of each other. But not sure. Any ideas would be greatly appreciated. Thanks in advance.
