The run is not finished yet, so they're in a dog run type run. We have tried everything to contain Miracle; adding more wire on top, securing all sides of the fence, etc. if she can't get out she will dig her way out. So she has become a free-ranger, our only chicken to free range all day. She stays near her flock, so we don't see a problem with it.
She is Miracle; the Chicken Who Cannot be Contained.
(We are home all day. If we have to go somewhere, all of the chickens are put inside the coop because if Mir can get out, anything can get in.)
