Invest in Hardware cloth and you'll never regret it. That stuff will stop just about everything from little weasels to large dogs and coyotes. And be sure to put the wire in the ground as well to have a skirt around your run and coop so that critters can not access their way into your run.Hi all! New to BYC and well, chickens. Hoping my fellow Michiganders can help a girl out!! Any and all advice will be much appreciated. Looking to start my coop out with some egg layers as we eat ALOT of eggs. Wanted to order me some chicks to be delivered by the end of Feb. but not sure if the ground will be thawed enough for the husband to build my coop and run. I'd like them to free range. Again, any and all advice welcome!! Thanks!!
