Oddly, I've been dreading this part far more than building the coop.
So my plan is a 10' x 20' run. 6 -1/2' high. Just a basic rectangle, nothing too fancy. I had thought about incorporating the nearby trees into the run, but decided the run should go the other way as the drainage is better (away from pool/hardscape).
The area has a little elevation to deal with, maybe 8-12 inches across the 20 feet of run. My plan is to build it so that I have braces every 4 feet on the sides and top. My goal is to not have to cut the hardware cloth any more than I have to, so if my math is correct, I should be able to go up one side (6.5'), across the top (10') and down the other side (6.5') and still have a 12 or more inches on either side for an apron. This is based on a 25ft piece of HW cloth. The run will be surrounded by a foot or more of rocks and paving stones as well so I am not too worried about predators digging under. Plus, my ground is really rocky so it's tough for anything to dig in it. All sides and top will have 1/2" HW cloth on it.
I plan to have a good sized door to the run as well, as I have a four wheeled yard wheelbarrow/wagon type thing I will likely want to bring in there occasionally. Maybe even a 4ft door (again, to limit cutting of the HW cloth).
My biggest issue now is not wanting to dig post holes and pour concrete. My town gets squirrely when it comes to permanent structures and permits, plus, the rocky ground become just rock after about 18in. What I would like to do is dig down until it's level, put in concrete blocks, and build the frame off of that. I might use treated 4x4s as the base plate of the framing, but im not sure if I need to. The other option is using my 4x6 posts directly on the concrete blocks and just connecting them at the ground level with treated 2x8s or 2x10s or something.
Has anyone done this before with success, or does everyone dig post holes?
