Minimum
Shelter + run + bathing water
4 sq ft/bird shelter + 15 sq ft/bird run + pool
Medium-heavy Swedish dual-purpose duck: ~4 sq ft of dry ground-level shelter per bird, 10–15 sq ft of run, and a head-submersible bathing pool. Calm and cold-hardy; keep in groups.

Recommended
Larger run with pond
6 sq ft/bird shelter + 25 sq ft/bird run + 6×4 ft pond
Larger run with refillable pond, shade, soft footing, and constant deep drinking water. Swedish Blues are excellent foragers — provide pasture rotation if possible.

Ideal
Pasture + natural pond
Locked night shelter + pasture with natural pond
Pasture access by day with a natural pond and secure night shelter. Excellent feather/skeletal health and a calm temperament that suits mixed waterfowl flocks.
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.
Keep a flock with a predator-proof house and run or free range. Robust and cold-hardy (developed in Sweden/Pomerania), they handle harsh winters with dry, draft-free shelter. Heavy and poor flyers, so easily contained by low fencing. Provide head-dunking water and bathing water where possible, shade in summer, and roughly 1-1.5 m² indoor floor per bird plus outdoor range with foraging.
Diet
Feed a waterfowl/poultry layer or maintenance pellet. Good foragers that take slugs, snails, insects and greens, helping with garden pest control. Supplement with leafy greens, grit and calcium for laying hens. Feed beside water.
Behavior & temperament
Dual-purpose (eggs and meat) and a popular hardy homestead/pet duck. Lays roughly 100-150 large white, blue-tinged or green eggs a year. Calm, friendly, quiet and good-natured — excellent for families and beginners; some hens go broody and mother well. The blue colour does not breed true: pairing two blues yields about 50% blue, 25% black, and 25% splash (silver) offspring due to the single blue dilution gene.
Health
Generally very hardy with few breed-specific health problems. The main 'issue' is genetic rather than medical — the blue plumage is governed by an incomplete-dominant gene, so colour is unpredictable and only blue-to-blue keepers must expect black and splash chicks. Standard waterfowl care (dry footing, shade, niacin for ducklings, bumblefoot prevention) keeps them thriving.
Tips, DIY & hacks
If you want to maintain blue offspring, understand the genetics: blue x blue gives a mix; crossing blue with splash or black can shift the ratios. The white bib should be a clean, single patch — heavily mismarked birds are common in non-selected flocks. Their calm temperament makes them ideal first ducks. Provide swimming water and they'll reward you with healthy plumage and active foraging.
