PVC coated galvanized steel wire mesh in building their coops? If so, what are the advantages? I have three, nearly four week old chickens and need to get my coop up pretty darned quick. Had NO idea they would get this big so fast and I'm thinking the brooder won't hold them for long. We live in New England and the winters are pretty harsh. Has anyone ever done double walls with insulation for a coop? Pressure treated wood or no? Building on a budget, but want to make sure the construction is sound and I can physically walk into the run area for cleaning etc. SO confuzzled and feeling out of my element right now but determined to make it go! Thanks so much for your patience and help!!
