I am about as frustrated as I have ever been. I am trying to set up the floor joists for my coop extention. It's going to be 8'x8'. I am, unfortunately, having to set it up on a slope. Not just any slope, but one that slopes in two directions! I am using a combination of cinder blocks and deck blocks with 4x4 posts. Half of one side is mounted directly to my other coop, (which, by the way, is not level.) I know the side mounted to the other coop is level. I also know the back side is level. My levels tell me that the other two directions and diagonally are only slightly off. The whole thing looks ridiculously crooked. I don't know if something is wrong with my levels, if I'm using them wrong, or if the whole thing is level and it's all just an opticle illusion. Anybody have experience with this kind of situation building their coops or sheds?
