I would like to expand my chicken run, however the only direction I can go is where the the septic lines run through to the drainage field, so driving posts is out of the question. I looked through the Coop & Run forum here last night till I was googley-eyed, and never found one that was build purely above ground. I'm envisioning the type that are attached to portable chicken tractors, but on a much larger scale. I'm thinking 8' wide by 30' long. Half of one side can be anchored to the barn, the last half of that same side can be anchored to the existing run where there are T-posts and welded wire fencing. If anyone has any suggestions or can direct me to a link of a similar run I would greatly appreciate it!
