Making headway on my 8'x8' coop. I will get the stairs, landing, and roof done within the next two weeks. I was wondering what materials to use for exterior wall weatherproofing? Right now the walls are covered with 3/4" plywood. I was thinking about vinyl siding which I priced out at around $60-$70 for all four walls. We get loads of thunderstorms/rain here in the spring/summer/fall, and in the winter tons of snow and temps well below zero. What weatherproofing materials would you recommend? Also, to insulate or not to insulate? I've read opinions on both. Gets really cold where we live. I am planning on running power to the coop for a light and outlet, and to hang a heating lamp. Here is where I am at with the coop build: Thanks!
