Good luck, @Kris5902 That's a lot of work having to push around those tractor coop's. I have the stationary one that we built from out of wood, and the attached secure pen is made from horse panels (top and sides), covered with 2" x 4 " galvanized no climb that runs 2 ' under ground, and then the smaller sized chicken wire over it. There is wood placed over it on the top of all of that to help with shade and extra protection.
