We are also in NC. Our pressure treated 2x4 & 2x6 frames that our 3 - 2014 & 2015 CP hoop coops are built on and doors framed with, have almost completely rotted out. In the process of removing the base framing (saving the lag screws for other projects hopefully), raising and widening the coops so that they are 10' wide and using a variety of bases. Cinder block, tin or stacked tires. We'll see which works best or which I like the best. Since the hoops will not be supported by the base, t-posts will be driven into the ground to keep the hoops in place. The backs will be redone and have the nest boxes installed. The fronts will be Rugged Ranch dog pen panels that already have the gates. I will add 1/2" HC to the bottom and 2x4" wire up higher. The cost in cinder blocks for one now 10'wX8+'l coop will be just under $93 + tax. I already have tin and tires I can use - coming from other projects.
Looking forward to seeing the rest of your build and WOW, those garden beds are nice!
