I'm planning my build of the run. I ordered a prefab coop, because I have no building experience, lol. I will have 2 to 4 full size hens. I want to make it tall enough so I can walk into, and cost is a big factor. I plan on making a wooden frame, with a "^" at the top that I can put a tarp on. What should I use for the fencing material? Does chicken wire only have to come up a certain height? I'd appreciate any advice.
