You can make square ones out of hog/cattle panels, too... wire them together in the corners. Cattle panels are usually 48" high (or more) with pretty large squares. Hog panels are usually 36" high (you can reach the bottom) and the spacing gets narrower toward the bottom (to keep piglets from squeezing out) and those are nicer because the small stuff that falls to the bottom isn't going to fall out. On one corner, you can just wire it in the center and near the top and bottom, use it like a door when it gets close to empty.
Typical lengths are 12' and 16' and nearly all farm stores, and some home improvement stores, carry them. I live in Nebraska so I'm always picking up used ones for nothing. I cut them with a 4" angle grinder and a .045" thick steel cutting disc.
