I have plans to build a run for my 52 and growing Chickens. Let me know what you think and other ideas. 1. One of my plans to make this out PVC pipe and sturdy farm netting about 12 feet wide by about 25 feet long. My plan includes arcing the PVC and secure the netting to the PVC. Very inexpensive compared to others. 2. My second idea is to make the same size with chicken wire and 2x4's. It is like a shed with chicken wire sides and chicken wire top. More expensive but long lasting.
