One of the drawbacks of our current chicken and duck enclosure is that it is small compared to the number of birds present. They immediately ate all the grass. On the other hand, it is next to the hay field, and such lush riches tempt the chickens to fly over the fence. We would let them free forage if we thought they would survive such freedom. Enter the cautionary tail:

We think a fox may be hanging out in our woods. This is on the back side of the garage, which is adjacent to the tractor shed...and the bird run. We have crafted the coops to discourage digging animals at night, but this was a daytime hit a little too close to home. So we gather green stuff for our birds and shoo them back into their enclosure when we find them wandering afield. We watched the escapees and found the path to freedom involved the gate. Michael added a wire to the top. We will see if this keeps the chickens penned but protected.
