In addition to these companies, there are others, including the famous Catawba coops, a company that will not only sell you a chicken coop; but will sell you the plans to build your own furniture grade chicken coop.
In Utah, the K9 Kennel Store sells coops, tractors, and even powder coated steel chicken runs and aviaries. An 8' X 8' chicken run with a corrugated roof sells for $625; predator protection bars to prevent digging into the coop are on added cost option, available for $200. You can order a coop door to connect your own coop to the run, or you can order a complete coop and run.
