We get lot2 of wind. 40+ mph isn't unusual, last week up to 75mph gusts when a storm blew through. I'm seeing lots of people building a coop and run and just setting the frame on top of bricks of various sorts. Will this stand up against wind or should it have at least corner posts anchored into the ground? 4x6 coop with an 8x10 run with the coop enclosed in the run.
