The cows are the stars of the show at Polyface Farms. The are manure machines, each putting out 50 lbs. of brown stuff a day. For three seasons of the year, they move from pasture to pasture, eating the grass and depositing fertilizer.
The chickens follow the cows in the pasture. The spread the cow patties and grow healthy on a diet of grass and bugs. During the winter, they are kept in multi-use shelters.
