The company retains ownership of the birds, and the grower is paid a return (usually about 3.5 cents to 4.75 cents per pound of broilers marketed) for labor and facilities. Contracts generally have incentive clauses for superior growers to earn extra money. These "bonuses" are earned by having lower mortality, producing more pounds of broiler on a given amount of feed, and having fewer birds condemned during processing than the average grower.
