Thanks for all your help. I do want a permanent run.I probably should have explained this, my yard is completely fenced. The run will only be about 10x20 and half of will lean against a 6 foot tall vinyl fence. Having it so small, I can afford to get attractive materials.The only predators would be my beagle and the occasionally dog I babysit. The reason I want it attractive, is family and friends spend a lot of time in the backyard and the pen would be one of the biggest focal points. Right now I have 3 Brahmas in a small, ugly run. I'm planning on getting on silkies, but I still want the run to be 6 feet tall to match the height of the other fence. Is this making sense? Thank you.
