Hello, I am having a problem with my duck/chicken coop. We at one time, had a snake problem so I had my boyfriend's father come out and fix it. He got wooden beams and placed them around the coop. He laid concrete to seal them in and leave no entry points for predators. That has worked very well in that sense. The new problem I face is that I am having a drainage problem. The ducks continue to swim in their water bowl which turns the dirt floor into mud. I sprinkle wood chips down but those eventually get muddy. I am not sure what to do. Suggestions please?
