Our quest to figure out the perfect coop setup continues. After seeing what commercially-made coops cost, husband is now on board with the idea of building our own, yay! We are looking at a large A-frame chicken tractor design which seems to fit our needs very close to perfectly - the Catawba Coops tractor, specifically. The only misgiving I have is the predator problem. We live on the border of a national park, and consequently we have pretty much every predator possible - coyotes, foxes, bobcats, raccoons, possums, rats, owls, hawks and probably something I've missed. We plan to put padlocks on all outside openings to defeat raccoons, and strong 4-mesh-per-inch hardware cloth on the outside run section, including the bottom. We also intend to extend the hardware cloth on the bottom out about a foot beyond the base of the run, staked down with metal tent stakes, in order to defeat diggers. Is this enough? Does anyone have any other suggestions? My worst nightmare is to order my baby chicks and raise them indoors, and they are all tame and we love them, and then see them all killed the first time we put them outside. I want the Fort Knox of chicken tractors!
