A neighbor had to tear down a brand new, poorly constructed two story deck. The new carpenter wanted nothing to do with any of the mess that the last guy left behind, including the framing materials. Everything that was destined for the scrap pile ended up in my yard and I have started building my "dream coop". Here in Austin, Texas, I am more worried about ventilation and keeping the air moving in the coop during the summers than about the few really cold days we might get each winter, so I am going to have the welded wire around the lower 18" of each wall and making up a good portion of the front wall.The wire and corner posts I bought new. The rest of this coop is built out of recycled lumber. I haven't decided what type of roof I will use, so I still have to frame and install the roof. But I may just go with a tarp for a while. Once I get the rest of the wall panels and wire installed and build the door, our 7 hens will be living in style!
