A massive French dual-purpose duck that looks like an oversized Mallard—the drake keeps the iridescent green head and claret breast. Bred up from the wild Mallard for the table, the heavy exhibition form is a slow-growing showpiece.

Minimum
Shelter + run + bathing water
4 sq ft/bird shelter + 15 sq ft/bird run + pool
A heavy mallard-derived duck: ~4 sq ft of dry ground-level shelter per bird (Rouens do not perch), 10–15 sq ft of run, and a bathing pool deep enough for head submersion. Heavy build = soft footing and good drainage to protect feet/legs.

Recommended
Larger run with pond
6 sq ft/bird shelter + 25 sq ft/bird run + 6×4 ft pond
Larger pen with a refillable pond, shade, soft footing, and constant deep drinking water. Rouens are too heavy to fly, so a 3-ft fence keeps them in; predators (raccoon, fox) must be locked out at night.

Ideal
Pasture + natural pond
Locked night shelter + pasture with natural pond
Pasture access by day with a natural pond, abundant forage, and a secure night shelter. Rouens thrive on diverse pasture and proper swimming water, which supports skeletal and feather health.
Life & growth stages

Egg
Birds develop inside a hard-shelled egg incubated by the parent(s). Egg size, shell color, and clutch size vary by species; the embryo develops over days to weeks before hatching.

Hatchling / Chick
Hatchlings are either altricial — naked, blind, and dependent on parents (typical of parrots and songbirds) — or precocial — downy, mobile, and self-feeding soon after hatching (typical of poultry and waterfowl). Down gives way to the first feathers.

Juvenile / Fledgling
Fledglings grow in their juvenile plumage and begin to fly and feed themselves, though they may still beg from parents at first. Juvenile feathering is often duller than the adult and is replaced as the bird matures.
Adult
Adults attain full body size and mature plumage, and are capable of breeding. Many species show distinct adult coloration, and in sexually dimorphic birds males and females differ in plumage, size, or markings.

Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Ground-level, predator-proof, dry-bedded shelter plus a run with bathing water (pool or pond). The heavy exhibition type is ground-bound and waddles, so it needs flat, dry footing and gentle slopes—deep mud and wet bedding cause foot problems. Provide shade; like other heavy ducks they handle cold better than heat. Low fencing contains them since they cannot fly.
Diet
Waterfowl/all-flock ration (with adequate niacin), oyster shell for laying females, and grit. They forage well for greens, insects, and aquatic life when given range. The big show type needs careful conditioning—enough nutrition to grow without becoming over-fat—while production Rouens eat more like a standard meat duck. Always provide deep, clean water for head-dunking.
Behavior & temperament
Calm, quiet, docile dual-purpose ducks—historically a premium roasting bird, now also a popular exhibition and pet duck. Layers produce only a modest ~35-125 eggs a year (lower in the heavy show strain). Their placid, slow nature makes them easy to handle but poor at evading predators. Sociable flock birds; keep more than one.
Health
The exhibition type's extreme size and low-slung 'keel' make it prone to leg/foot issues, bumblefoot, and difficulty mating and walking on rough ground—a conformation welfare concern in the heaviest birds. Like all ducks, ducklings need niacin to prevent leg weakness. Slow to mature; keep bedding dry and footing soft. The lighter 'production Rouen' is hardier and more practical.
Tips, DIY & hacks
Decide which type you want: the giant exhibition Rouen is a show/pet bird that grows slowly and needs careful management, while the smaller production Rouen is a better all-round homestead duck. Provide easy water access for mating success in heavy drakes, keep ground dry to avoid bumblefoot, and don't expect many eggs—these are kept for looks and meat more than laying.
