Rouen duck Rouen duckling is identical to the Mallard duckling in terms of plumage coloring. In North America, two distinct types are bred: the common, or production-bred, variety that is larger than a Mallard but has a typical duck conformation, and the much larger and squarer standard-bred variety. The production variety normally weighs 6–8 lbs (2.7–3.6 kg) while the standard-bred weighs 9–12 lb (4.1–5.4 kg). Rouen ducklings can be distinguished from wild mallard ducklings by the presence of a second stripe which runs across their face, just under their eye, whereas mallard ducklings have only one stripe which runs across their eye.
Maritime, Fluvial and Harbour Museum of Rouen not far from the new Gustave Flaubert Bridge. The building was built in 1926, and was called Building M until 1966, when the Autonomous Port of Rouen ("Port autonome de Rouen") was created. Until the 1970s it was leased to the Schiaffino Company, which transported wine between Rouen and North Africa and used it as a wine warehouse until a special wine building was built, and thereafter mainly for fruit. The building was subsequently used by a series of different companies until 1984, when it became surplus because of insufficient size. Maritime, Fluvial and Harbour Museum of Rouen The Maritime,
