I came across this product and thought I'd post a link. I thought it would be great for "non-handy" people looking for a sizable pre-fab option. Perfect for renters who want to disassemble and take their coop when they move. You can add a fully enclosed peaked roof and canvas cover to the run to provide shelter that allows a person to stand up inside and protects from aerial predators. Some will argue it's pricey and lacks some chicken-specific features but assembly is a breeze and it's so easy to expand the run. With a few simple modifications you could have a well protected coop and run in a couple hours.
