Is chicken wire sufficient against racoons? I realize it won't keep out coyotes and other large predators. We do have some coyotes & foxes here, but by far my biggest problem is coons---lots and lots of them. I just built a hoop house (but with solid sheet-metal wall for the ends), but now want to build another (more mobile) version. I plan on using chicken wire & 1x4s for the end walls.
