One year, I planted oat hay, and the down side of that hay was every bale had a mouse nest under it. When it came time to feed the cows, I'd load the hay into my truck. Every bale I picked up had a dog, a cat, and half dozen chickens right there waiting. When I'd pick up the bale, mice would be running everywhere, and dog, cat and chickens would a big mixed up scramble, going as fast as they could, chasing down mice in every direction. The chickens would peck the mouse and kill it, then choke down the entire mouse, head first.
