After looking at all sorts of runs on here, I think I may be leaning towards making a hoop run. I initially was going to do a run with 2x4's, wire, and hardware cloth, but I think it might be easier to make a hoop run. My questions are: If you make a hoop run, what is the width of the run if you use a 4x16 cattle panel? I've looked at a bunch of photos and I'm trying to figure out how far apart you would put metal stakes that are supporting the cattle panels. Can you just attach the panels to metal stakes in the ground or do they need to be attached to a 2x4 frame of some kind along the ground? Are cattle panels difficult to bend to form the hoop? Also, how do you attach a hoop run to a coop? Finally, what would the height be of the coop at its tallest point (the middle)? Thanks so much!
