I am having trouble building our run. We tried pvc but it is too wide and the pvc sagged. We then added 2x4 supports but there was still some sagging. We tried tying the sagging parts to trees but I was not confident in its ability to hold snow, predators, etc. There are trees that I could wrap the fencing around but digging down to bury the fencing is tough because of all the large roots. I have a roughly 22x35 trench dug but can change it if needed. Should I use the trees, bury some posts, build an A frame with thicker pvc, etc? Please throw me some suggestions on how to build it! Also, I live in southeastern MA and although I had been looking at 1/2" poultry wire I must have ordered the wrong one and now have 1". Are there predators in this area that can get into that? I have fisher cats, fox, and raccoons that I know of. Thank you in advanced!!
