I guess I'm probably fretting like a mother hen but it never hurts to ask. I let my three one plus year old hens out in the morning and they'll strut around the run for a minute. Then they take these humungo-poos! I'm not kidding. They're not quite the size of a tennis ball, but way bigger than a golf ball. They've been doing it for as long as I can remember but a particularly large one spooked me this morning. Should I be worried?
