This wind is killing me. Pens are shuddering in the wind. I have 3 4x8 dome pens with doors. I have 6 bungees on each door keeping them closed but the pens are shaking so bad one of the doors just popped open. They're getting ziptied closed screw it.
Run a rope through pens tying a couple cinder blocks to each end. In a pinch I can hold down about 10 pens per rope. Should keep pens from outright rolling.
