I had let the girls out to free-range one day early on in their lives and it just so happened that the neighbor came by with his very very large brush mower thingy and scared them all away. That night I did a head count and found out I was missing one. I looked and looked but couldn't find her and I thought she was gone for good. However, the very next morning I found her INSIDE the run sleeping under a bush. She must have jumped back in somehow. She was SO relieved to be back with the girls. This was before I had my rooster, now he keeps everyone together.
