Rouen
Large mallard-coloured duck bred for show and table — not a strong flier.
By the WARN Research & Conservation TeamChecked against IUCN Red List & CITES sourcesLast updated
In brief
The Rouen is a heavy French duck resembling a large mallard in colour but bred for show and table. Its defining trait is ornate mallard-patterned plumage on a slow-moving, docile frame unsuited to long flight.

| Origin | France |
|---|---|
| Size | Heavy (2.7–3.6 kg) |
| Typical weight | 2.7–3.6 kg (6–8 lb); one of the heavier duck breeds |
| Lifespan | 8–12 years |
| Plumage | Rich mallard markings — green head on drakes, brown on ducks, with blue speculum feathers. Plumage is dense and waterproof with regular preening. Rouens moult seasonally; provide water for bathing during feather regrowth. |
| Temperament | Docile, slow, ornamental |
| Best suited to | Best for keepers wanting ornamental or traditional table ducks with space for slow foragers. Rouens suit calm gardens with ponds and tolerate children when handled gently. Avoid steep ramps and excessive stairs due to body weight. |
History & Origins
Rouen ducks were developed in the Normandy region of France as a larger, slower version of the wild mallard for meat production. The breed crossed to Britain and America in the nineteenth century and entered exhibition standards. Industrial Pekin and hybrid ducks largely replaced Rouens commercially, but the breed persists in show circles and heritage farms.
Rouen Fun Facts
- Rouens look like oversized mallards but cannot fly well due to body mass.
- Standard Rouens take nearly two years to reach full size.
- Show Rouens are heavier and slower than production strains.
- The breed name comes from the city of Rouen in Normandy.
Rouen Common Health Issues
Conditions seen more often in this breed, and how owners and vets help manage them. This is general guidance, not veterinary advice — always speak to your vet.
Obesity
Heavy breeds gain weight on high-energy treats with limited exercise, worsening leg and heart strain.
Care: Measure feed, encourage foraging and avoid bread or scratch grains as dietary staples.
Bumblefoot
Extra body weight increases pressure on foot pads when landing from perches.
Care: Keep ground soft, perches low and treat early infections before lameness becomes chronic.
Joint strain in heavy birds
Slippery surfaces and steep banks stress hocks and hips in Rouens.
Care: Provide gentle ramps, non-slip mats and swimming water to support buoyant exercise.
Ducks deserve proper care
Domestic ducks are often bought as Easter gifts or pond ornaments without understanding their social, dietary and veterinary needs. These guides support responsible keeping and WARN's broader animal welfare education mission.
