The chest is brown while the wings are gray or brown, and they may have green, white or blue stripes on the wings. Standard Rouen ducks are challenging to raise because the adults are so heavy that they can crush their own eggs if allowed to sit on them. The standard Rouen Duck has a more square body. Their keels are straight and level. Breeders must be careful about the keel that is considered attractive in show, since taken to an extreme, the male duck then has trouble breeding.

Water-proof feathers of Rouen duck
A special feature that the Rouen duck has is its water-proof feathers, even when the duck dives underwater, its downy under-layer of feathers will stay totally 100% dry. There is a special gland called the "Preen Gland" also called Oil Gland or Uropygial, that produces oil that is near the Rouen duck's tail which covers and spreads the outer coat of the duck's feathers, which makes the duck water-proof.
Features of Rouen ducks feet
Rouen ducks have webbed feet, that makes them act like paddles, designed for swimming. They push their webbed paddle feet back in a kicking motion, this allows them to move swift through the water and when the feet come back, they will close for less water resistance. The Rouen duck's paddle feet do not feel cold, even when it swims in cold icy water. The webbed feet makes a Rouen duck waddle instead of walk. The Rouen duck’s feet have capillaries which help blood flow to their feet. The warm blood flow down the leg and creates a heat exchange system. When the blood flows down the leg, it meets the cold blood and is warmed up to keep the ducks feet warm. Rouen ducks feet are thin because they contain soft tissue and few muscles.

Features about the Bill of the Rouen Duck
A "bill" is what is call a duck's mouth. There are no teeth in the ducks bill, they have rows of thin bristles, which helps them to filter pieces of nutrition out of the water. Rouen ducks swallow there food whole and it goes to an organ called a gizzard, were the food is first ground up and than moves on to the stomach. The different bill shapes and sizes for finding food, has over time mutated to fit each environment. The bill is flat and broad and has rows of fine incision along the outer edge called "lamellae". meaning a thin membrane, plate, scale or layer, as of cell wall or bone tissue. The larnellae helps the duck to clutch food for feeding.
Underneath the water-proof coat are downy soft fluffy feathers which keep the ducks body warm. Ducks keep clean by being able to turn their heads completely backwards, and put their beaks into their feathers by preening themselves.
Male Rouen ducks will guard their nest by chasing away other ducks. Once the female lays 5 to 10 eggs, she will start to sit on her eggs to keep them warm so that they can hatch into baby ducklings. The eggs will hatch on average within 26 to 28 days. Baby ducklings are able to fly within 5 to 8 weeks. Rouen ducks will lay more eggs, when there is more daylight, that's why farmers will keep the lights on in the ducks house for longer periods of time.
Rouen ducks see in color with very good vision and can see well underwater. Rouen ducks have three eyelids the third eyelid called nictitating membrane. They have a top and bottom as well as a third eyelid that is found on the side of the eye. The Rouen ducks eyelid blinking acts as a windshield wiper to clear the eye. This helps to see when diving under water can also help the eye from drying out while flying. This is an act of constantly cleaning and keeping the eye moist.
