@dheltzel How did you get the 16' cattle panels home for your hoop coops?
A few years back we had a family run a corn maze on the farm and they had animals in pens made from the cattle panels. When they closed up shop, they offered the used panels to me for $4 each. Score !!
I've heard you can bend them into an 8 ft bed, they would be about 6 ft high. You should tie them down really well, but they don't make a lot of wind resistance. I've hauled 16 ft cattle gates in an 8 ft bed a couple of times. That was always scary, I put something real heavy in the end stuck in the truck. I wouldn't recommend that for the panels though, they would flap too much and probably "escape" the bed.
