People have asked for pictures of our chicken tractors. These are not great photos, but help you get some scale. This one is 8'x8'x18". Part of the top is wire mesh, and part has lightweight metal roofing for rain and sun protection. We use an automatic water-er that utilizes a separate bucket outside of the tractor with a tube which runs to the inside of the tractor. It is very easy to keep filled. They are moved to new grass each day.
