Many years ago I had a coop that we would move around with our tractor. I had a temporary fenced run that was also moveable. The county came up and wanted to include the coop as a building on the property. We told him it was a chicken coop and we moved it around, we are very rural on a dead end road. It took quite a bit of convincing but eventually he agreed. He could plainly see there were chickens in it. Originally it was a brooder coop but we eventually moved it out to where the outer coops are. The coop was on skids. There were wheels attached to the run.
