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.
