Eggplucker...absolutely love your coop, run, and enlarged run surround design!!! I just finished my new coop 4'x6' and run 12'x6' for my six baby girls that is similar to yours in looks, the inside of mine is smaller 4'x 6' with a window, four nesting boxes, and two roosts looking out the window. We have many raccoons here so I opted for hardware cloth on run walls, under the full length and width of it, then landscaping cloth over that, and topped with pea gravel. No critters getting in there! Oh! And hardware cloth over the window too. After seeing your wonderful design, I will start on an enlarged run like yours in the spring. Thanks for the great pics! You are such a wonderful hubby making all that for your wife! Check out my BYC page to see my coop.
