Boy, I'm going to sound dumb on this one, but does anyone have plans for a pcvp pipe chicken tractor. The pipe part, I'm guessing, would be the easy part, but what type of netting would you use, where do you get it, and how would you build a gate or a door into it? And, is it expensive? We are not real skilled at this. We want a big one; 12X6 or so. I couldn't find anything when I searched.
