I am building a rectangular PVC chicken tractor to rotate in my sheep pasture, and want to cover it with ANYTHING but chicken wire. I have in mind some sort of pliable plastic mesh that will contain the chickens, which could be zip tied to the PVC pipes. It is going inside a portable electric mesh fenced area, so this does not need need to keep out predators since the portable fence will take care of that. Any thoughts on plastic mesh that would suit? I am SO tired of dealing with chicken wire. Thanks in advance.
