Poultry farming is the practice of raising domesticated birds, such as chickens, turkeys, ducks, and geese, for their meat, eggs, and feathers. It involves managing the health, nutrition, and welfare of the birds, as well as the housing, equipment, and land used for their care. Poultry farming can range from small-scale backyard operations to large commercial enterprises, and may involve various production systems, such as free range, organic, or battery cage systems
