Ill show you some pictures of what I have done for pens using chain link panels, flight netting, a portable garage frame and very heavy truck tarp. I have just watched the want ads and picked up what I can find where I can find it. Some times I have to think for a while to figure out how best I can put it together for something usable. My poor wife thinks Ive lost my mind when I haul something home on the trailer.
The snow slid off the chicken coop this winter and took out some fight netting and rain gutter so Ill have to put it back up but during the winter they are all free range and sleep on top of the netting supports and shelters anyway!
The center suports for the netting are wire spools with a post in the center hole.
Built an end wall in each end of portable garage frame!
Covered the frame with a very heavy Trucker tarp!
I devided the encloser in half with a straw wall!
Also have a couple of Fiberglass Truck Air Deflectors that I picked up "FREE" that make great shelters!
The Pens for the turkeys very in size but are roughly 14' Wide X 30' Long with a 10' X 10' enclosure!
I have never keep more than 6 birds in each pen
