Polyface raises pastured meat chickens, egg layers, pigs, turkeys, and rabbits. The diversity in production better utilizes the grass, breaks pathogen cycles, and creates multiple income streams. The meat chickens are housed in portable field shelters that are moved daily to a fresh "salad bar" of new grass and away from yesterday's droppings. All manure is distributed by the chickens directly onto the field. His egg-laying chickens are housed in mobile trailer-style coops (called "eggmobiles") that follow four days after the cattle, when flies in the manure are pupating; the chickens get 15% of their feed from this. While scratching for pupae, the chickens also distribute the cow manure across the field.
