Pekins are the most common domestic duck. Pekins are a large, hardy breed with excellent egg production if appropriately managed. Over the years, selection by breeders has produced a duck that can often be processed by 40 days of age at a live weight of seven pounds. Though their feed efficiency does not match that of chickens, they can still produce one pound of live weight from 2.5 pounds or less of feed. They do not fly and do not usually hatch and raise their own young. Pekins are very talkative, are good layers, and make good pets for old and young alike. Full-grown adults weigh 8 to 12 pounds, and females lay approximately 150-200 extra-large white eggs a year. The adults are pure white, and the ducklings are a bright yellow. Pekin ducklings have yellow down feathers with orange feet and beaks.
