I've been searching all day, and have yet to find a satisfactory answer either in forum OR in photos. So here goes: I'm building a raised coop with attached run on a slope. What recommendations can you give me so that I can build the coop on a flat surface and then install it level where I want it? I was thinking leveling it with concrete blocks under the vertical posts, but was unsure if this would be stable enough. FYI, the run itself will be built in place to follow the slope I'm building on. Just the coop will be built elsewhere (my garage). It's not a TERRIBLY steep slope, about 20*, but I do have to level the coop. Thanks!
