I was worried as I was at work all day. Came home and all is well.. We have 2 umbrellas in the run, under the shade cloth. That shade cloth held them in. Everyone was accounted for, I am so happy no chicken got blown around or out of the run. Plus our girl keeps a good eye on her flock.There's a pretty good wind blowing out there today, but it doesn't seem to be bothering them much as they are still being active out in the run.
