Jim Christopher, president and CEO of Concord Farms, Inc., is on a mission to convince Americans to eat more duck. In 1987, the farm plans to process eight million ducks, a doubling of the number processed in 1985. The company can process up to 24,000 a day. The finished product is then sold in all fifty states and abroad. Duck feathers sold for jackets, comforters, and pillows account for 10 to 20 percent of company revenues, which were estimated at over $41 million in 1986.
