Hi, I just started raising backyard chicken. I have a open-air chicken run and rains can get in from the side. It was raining heavily last week and the chicken run is muddy and very smelly now. I searched in the forum and a lot of people suggested to remove the dirt in the run and use sand instead. I was wondering if not using sand, is it a good idea to just place a big plastic board in the run that is heavy enough, so that chicken can walk on that. Well, not grass anymore for sure. I believe people have thought of this before. Would love to hear the pros and cons regarding that. Thanks, Alex In the beginning I used American Saturated Felt Roofing Paper as the roof and it turned out that it's too soft to guide the water. Unfortunately that's when we had the heavy rain. So I changed the roof to the corrugated PC board. This is from the left side of the run. From the top Top with my three red sexlinks. From the right side. Inside the run. You can see the mud and chicken coop.
