It really doesn't have to be that complicated. Here's one of my runz. Just some 4x4 fence posts, welded wire and hardware cloth. Dig in the posts, attach the fencing, put some over the top, you're done. Please note that the 2x4" welded wire will keep out most predators, but will not stop a mink or weasel. For that you need to encase the whole run in hardware cloth, and make sure there are no small gaps in your fence. Now take a deep breath and go over to the Coop and Run Design section of the forum and get some other ideas.
