Sorry for the double posting. Mods, please delete, I accidentally submitted twice. Hi everyone. My shed was finally delivered and I'm starting to convert it into a coop. Here's some pics of what I have so far. The question at this point is: how to protect the raw edges of the window openings. I am wondering if I can put z flashing on top of the T111 and then fasten it to a 1x2 that I'd fasten to the inside of the window opening. Edges and corners would be sealed with caulk (polyurethene?). I'd also first prime the edges of the windows with Kilz. The thing with this setup is that I would also have a surface to fasten the hardware cloth to. What'cha all think? The window openings: The roosting area: The poopboard is an old piece of countertop, 32 inch wide, and some OSB in the corner. On top of that will be washingmachine pans for catching the poop and easy cleaning. The countertop rests on recycled kitchen cabinets with the doors removed for nesting boxes, and 2x6 lumber that was left over from construction of our house to support it at the front and the sides.
