If you checked out my Bitchute channel, I have three videos that show my various setups. I use galvanized electrical conduit welded together. Then I attach the chicken wire using .032” safety wire. It’s very cheap, relatively, simple as hell to construct and nearly bulletproof. IF I lived in the county and Wile E Coyote was a problem, I’d use 1/4” hardware cloth held down with steel strips and self taping drywall screws.I plan to use something heavier than chicken wire, because I'd like this to be a permanent thing attached to the big coop. He said he'll have it up by the first week of May, so my fingers are crossed. 2 x 4's are pretty sturdy, and I'd like it to be tall enough to walk in.
