until today. We let our chicken out of the pen late in the afternoons to hunt for bugs. Today I had a friend stop by and we lost track of time. When I realized it had turned dark I also realized I hadn't herded the chickens back into their pen. I paniced and sent my daughter out into the yard with a flashlight to look for them figuring we would find them roosting on something. Instead, they had gone back to the pen and into their coop by themselves! All we had to do was shut the door. Boy, that sure beat moving about the yard in the manner of a sheep dog.
