Appenzeller Spitzhauben

Tall coop + secure run

4 sq ft coop + 10 sq ft run per bird, 4 ft roosts

Spitzhaubens (4–5 lb) are alpine landrace birds and natural tree-roosters. They need tall roosts (4–6 ft), 4 sq ft coop floor, and a 10 sq ft run minimum. V-shaped crest doesn't impede vision but get wet easily.

Covered run + roost ladder

5 sq ft coop + 15 sq ft covered run per bird

Covered run with branch ladder and clutter, deep-litter coop, dust bath. Spitzhaubens hate confinement — a small flock cooped tight will pluck each other. Cold-hardy; mediocre-to-poor in heat.

Free-range mountain-style

Free-range + 6 sq ft coop, tall trees / hedges for cover

Free-range a wooded yard with tree perches they can flap up to at dusk, locked in a predator-proof coop overnight when possible. Closest to their Swiss alpine origin — self-sufficient foragers laying ~150 white eggs/year.

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.

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.

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.

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.
