As you can see from the photos, I started out with a frame. This frame was previously my daughters green house but after my chicken frenzy 8 coops wasn\'t enough and I needed to build one more. What better than to use the existing frame from the green house. I had old barn boards left over from my barn build I used for siding and some extra tin from the garage build. I did have to purchase the wire and 2x4 for framing the run from Menards. The windows frames I got in a trade for some other windows I had been hanging on to. It was a basic build for me along with help from my 14yr old son, he always loves to help out mom with her projects.
