At dawn, the chickens in an eggmobile (portable henhouse) at Joel Salatin's farm in Shenandoah, Virginia are released to spend the day pecking in the pastures that cattle have just vacated. (From the book What I Eat: Around the World in 80 Diets.) The chickens spend the day eating insects, grass, seeds, and undigested bits in the cattle manure (helping to scatter it in the process).
