Coops, coops, coops... That's all one ever hears.. I can find at least 200 examples of coop designs on this site. What's hard to find is examples of how people frame their runs. Did you cement 4x4s in the ground and build off that? Did you bolt 2x4's together and tack them into the ground with long aluminum nails? I really want to see a few detail pictures of your runs, showing how the walls are built, how you covered it and if you wish you did anything differently. Thanks a ton!
