well it's not in large coop articles.. I did a seach for cattle panels and before my computer died I found something similar w/- much info . I think I got to page 17 in the seach...
someone did this.. they put a 2x4 on the barn wall at the height that worked... made a base.. stuck one end of the cp under the wall 2x4 and put the other end in the base... I am looking for that build...
