I have something similar, but it has a top to prevent fly aways. You could attach netting to accomplish the same. Mine's way too small now that I have more birds, but I did use it for a while to let them tear up the side yard when I was outside working - once I was done with yard work, the chickens got put back in their run too.
More recently I've used it to break broodies and transition chicks from brooder to coop, so it wasn't a total waste of money.
