I started building the coop/run this week and the more I read the more nervous I'm becoming! I live in a residential area with fenced in yards (6' high fences between neighbors) and the predators I am concerned w/ are hawks, possums and mice. I have never seen a raccoon here but the neighbors say they have- so not 100% but they are probably lurking, too. Has anyone here been completely successful at securing their run/coop? I'm terrified of doing something wrong and jeopardizing the hens! So far I'm making it an enclosed run 8L x 8W x 6H and will use 1/4" hardware mesh. I'm just wondering though if even that will be enough?
