We live in New Jersey and wanted a safe, dry, and winter enjoyable covered run for our chickens. This is our first time having chickens, as well as, building a coop and run; and to say the least it was a learning experience. We purchased corrugated roofing at our local Home Depot and let me tell you it is the thinnest, flimsiest, cheapest-quality-yet-so-overpriced thing!!!! Any ideas for something sturdier that will hold snow and help water run that isn't ridiculously priced and where I could get it! Thanks!!
