I got the 10x10 with a height of about 6 feet or so. It’s perfect and my two chickens love their new spacious run. Only problem for me is we ran out of chicken wire as well as zip ties and I just think they should make sure purchasers have plenty of that to ensure we do not run out. I had to use some old chicken wire for the door and my own zip ties. Other than that it’s great and I’m satisfied with this purchase.
