About the Cayuga Duck

Cayuga ducks are a distinctive medium-to-heavy domestic duck breed best known for their beautiful black plumage with a brilliant beetle-green iridescent sheen. In sunlight, their feathers can reflect shades of green, blue and purple, giving them a striking appearance.

They are a practical dual-purpose breed, traditionally valued for both meat and eggs, while today they are also popular as ornamental, exhibition and backyard ducks. Cayugas are generally calm, relatively quiet and good foragers, making them suitable for free-range environments where adequate water, shelter and predator protection are provided.

One of the breed’s most unusual characteristics is its egg colouring. Cayuga females can lay eggs with a dark grey to almost black coating, particularly at the beginning of the laying season. The coating generally becomes progressively lighter as the season continues, with later eggs often appearing grey, pale or nearly white.

Another unusual characteristic is that white feathers may appear as females age, often becoming increasingly noticeable after successive moults. This is a normal feature of the breed and does not necessarily indicate crossbreeding.

History & Origin

The Cayuga is an American duck breed developed during the nineteenth century. Its exact ancestry is uncertain, although the breed became established in New York State, particularly around the Finger Lakes region, and takes its name from Cayuga Lake and the Cayuga people of that area.

Cayugas were bred as practical farm ducks and were valued for both meat and egg production. Before the Pekin became dominant in commercial duck production, Cayugas were an important table breed in the United States.

The breed later became increasingly valued for exhibition and ornamental purposes, particularly for its distinctive glossy black plumage and brilliant green iridescence. Today, Cayugas are kept as both productive backyard ducks and striking exhibition birds.

Cayuga in Australia

Cayuga ducks are an established heavy duck breed in Australia and are bred for exhibition, ornamental purposes and as practical dual-purpose birds. They are recognised within Australian poultry standards, where their characteristic lustrous green-black plumage, heavy body and correct breed type are important features.

Cayugas are generally docile ducks and tend to remain closer to home than some of the lighter, more active breeds. Their relatively quiet nature can also make them suitable for backyard and small-property environments, provided they have appropriate housing, water and protection from predators.

The breed has also contributed to Australian poultry history: the Australian-developed Watervale duck is reported to have arisen from a closed flock of Cayugas in South Australia during the 1980s, although alternative accounts of its ancestry also exist.

Characteristics

Egg colour: Highly variable. Eggs may be dark grey to almost black, grey, blue, blue-green, greenish, or pale grey to white. The darkest eggs are generally produced early in the laying season, with colour often becoming progressively lighter as the season continues.

Egg size: Large.

Average egg production: Approximately 100–150 eggs per year, averaging around 2–3 eggs per week.

Weekly egg figures are annual averages. Actual laying varies with age, season, daylight, nutrition and individual bird.

Day-old sexing: Cayuga ducklings cannot be reliably sexed by colour or markings. Sex becomes easier to determine as they mature through differences in voice and, later, the development of the drake’s curled sex feathers.

Temperament: Generally calm, docile and relatively quiet. Cayugas can become friendly and confident around people with regular handling and are usually good free-range foragers.

Broodiness: Females may become broody and can make attentive mothers, although broodiness varies between individual birds.

Notable features: Cayugas are best known for their striking black plumage with brilliant beetle-green iridescence. Their eggs are equally distinctive. The dark grey or almost black appearance seen particularly early in the laying season comes from a dark pigment deposited as a coating on the outside of the eggshell. As the laying season progresses, less of this coating may be deposited, producing eggs ranging through grey, blue-green and greenish shades to much paler colours.

Genetic Anomolies: Cayuga ducks carry the Extended Black gene, which produces their characteristic solid black plumage. The brilliant green sheen seen on high-quality birds is not a separate pigment, but an iridescent effect created by the structure of the feathers reflecting light.

As females age, they commonly develop increasing amounts of white feathering, particularly after successive moults. This can occur in genetically pure Black East Indians and does not necessarily indicate crossbreeding.

Hardiness: Cayugas are generally hardy, robust ducks and good foragers. They require clean water, shade during hot weather, dry shelter and secure protection from predators, particularly overnight.

Rare Breed Status

The Cayuga is currently listed as Watch by the Rare Breeds Trust of Australia. The RBTA lists it as a standard/large duck, with no bantam form. The Of Concern category indicates low presence and/or low breeding-flock ratios in Australia, meaning continued breeding populations are important to the breed’s long-term security.
