We lost 9 adolescents early on by letting them free range too soon so some protection was in order. I had this 1 1/2" pvc leftover from another project, got the appropiate fittings and cut and glued this frame together. It's covered in 1/2" hardware cloth and attached with zip ties.I left enough extra on the coop end to screw the wire to the coop. It's light enough my GF and I can move it when the kids get big enough. 4'x4'x12' You can see the access door to the coop so they can get to food and water. Hope I gave someone an idea.
