Adults
Fully mature adult Pekin ducks weigh between 8 and 11 pounds (3.6 and 5 kilograms) in captivity. Their average lifespan (if not eaten at an early age) is about 9 to 12 years. Their external feathers are white, sometimes with a yellowish tinge. This is more obvious with ducks that have been reared indoors and not exposed to sunlight. The ducks have a more upright stance than dabbling ducks, and possess an upturned rump. The eyes of this duck appear to be black when seen far away, but up-close one sees a grayish-blue colored iris.
An adult Pekin will lay an average of 200 eggs per year if it does not try to, or is prevented from, hatching them. They will normally only lay one egg on any given day. They will lay their eggs in what they consider to be a safe place and will often lay where another duck has already laid (egg dumping). Ducks can be tricked into laying eggs where desired by placing a golf ball or similar object in a place where they might normally lay.
Pekin ducks are less "broody" than other ducks which means they will incubate eggs less frequently and they are more likely to abandon their nest before their eggs hatch. Hens can be used to sit on the duck eggs, or they can be incubated artificially.
Pekin ducks, for the most part, are too heavy to get airborne. While some individual ducks may be lighter and capable of short bursts of vertical flight, clipping their flight feathers (pinioning) is generally unnecessary. They are gregarious and will usually group together with other ducks.
As with most waterfowl, the Pekin duck has feet perfectly adapted for paddling through water but is also capable of walking while foraging and exploring as well. If keeping ducks, be sure to remove items from their environment which may cause tripping or stumbling, and house them on natural surfaces, such as grass, hardpack, straw, or sand which is gentler on the bones and ligaments, will not abraid the sensitive surface of the webbed feet, and is easy to keep clean. Ducks are happiest when they have free access to clean, safe water in which to swim and mate.

Famous quotes containing the word adults:
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
“Most adults will do anything to avoid going to a party where they don’t know anyone. But for some reason we may be impatient with the young child who hesitates on the first day of school, or who recoils from the commotion of a birthday party where there are no familiar faces.”
—Cathy Rindner Tempelsman (20th century)
“Above all, though, children are linked to adults by the simple fact that they are in process of turning into them. For this they may be forgiven much. Children are bound to be inferior to adults, or there is no incentive to grow up.”
—Philip Larkin (1922–1986)
