Crested Blue Swedish Duck: Profile, Facts, Eggs, Traits, Color

crested blue swedish duck

The Swedish Blue Duck, known as Svensk blå anka in Swedish, is a distinctive breed of domestic duck originating from what was formerly Swedish Pomerania, now part of northwest Poland and northeast Germany. Emerging in the nineteenth century, it bears similarities to other duck breeds but is characterized by a unique cluster of fluffy feathers atop its head, known as a crest. These ducks are primarily kept as pets or ornamental birds, appreciated for their unique appearance. However, it’s noteworthy that not all offspring of this breed will inherit the crested trait. Additionally, male ducks may exhibit behavior such as pulling out feathers during breeding season. In this article, I am going to describe Crested blue Swedish duck

Crested Blue Swedish Duck: Profile, Facts, Eggs, Traits, Color

One of the defining features of the Swedish Blue Duck is its crest, a distinctive cluster of fluffy feathers located on the top of its head. This characteristic sets it apart from other duck breeds and adds to its appeal as a decorative fowl. The crest can vary in size, with some individuals displaying particularly large crests. However, it’s important to note that the presence and size of the crest may not be uniform across all ducks of this breed. Furthermore, the crested trait may not be consistently passed down to all offspring, resulting in variability within the population.

Historical Background of the Crested Blue Swedish Duck

Origins and Emergence: The Crested Blue Swedish duck originated during the 19th century in what was then Swedish Pomerania, now part of northwest Poland and northeast Germany. The first documented mention of this breed dates back to 1835.

Introduction to America: In 1884, some Crested Blue Swedish ducks were exported to America. Recognizing its unique characteristics, the American Poultry Association added the breed to its Standard of Perfection in 1904 under the name “Swedish”, with the sole color variation being “blue”.

Conservation Status: Despite its historical significance, the population of Crested Blue Swedish ducks in Sweden is alarmingly low, with only 148 breeding birds reported. The Food and Agriculture Organization of the United Nations listed its conservation status as “critical” in 2007, while in 2014, it was classified as “endangered-maintained” in Sweden. Limited data is available from Ireland, the only other country reporting the breed. In the United States, the American Livestock Breeds Conservancy lists it as “watch”, indicating a breed with declining numbers.

Challenges in Exhibition and Breeding: The Crested Blue Swedish duck faces challenges in becoming a popular exhibition breed. Specifics regarding wing coloration make the breed difficult to standardize, often discouraging breeders and hobbyists from owning or breeding them. These complexities may hinder efforts to preserve and promote the breed.

The Role of Swedish Blue Ducks as Pets

Swedish Blue Ducks are primarily kept as pets by enthusiasts who appreciate their unique appearance and charming demeanor. As domesticated birds, they thrive in environments where they receive proper care and attention from their owners. Despite their ornamental value, these ducks can also serve practical purposes on farms or in backyard settings, providing companionship and entertainment. However, owners need to be aware of the specific needs and behaviors of this breed, including potential challenges such as maintaining the crest’s condition and addressing breeding-related behaviors exhibited by male ducks.

Crested Blue Swedish Duck Genetics

Physical Description: The Crested Blue Swedish duck is characterized by its medium size and distinctive globular crest. It features blue plumage with a heart-shaped white bib on the front of the breast, adding to its unique appearance.

Genetic Considerations: Breeding Crested Blue Swedish ducks requires careful attention due to the presence of a lethal gene associated with crest production. Special mating considerations must be made to ensure the health and viability of offspring.

Blue Gene (Bl): The blue gene (Bl) specifically affects black plumage, resulting in blue plumage when present in the heterozygous state (Bl bl). Plumage colors other than black are unaffected by the blue gene.

Mating Patterns: When blue (Bl bl) males are mated with blue (Bl bl) females, the resulting offspring exhibit a specific ratio of plumage colors:

  • 1 black (bl bl)
  • 2 blue (Bl bl)
  • 1 splash (Bl Bl), characterized by white plumage with a blue cast.

Variability in Plumage: Crested Blue Swedish duck chicks obtained from breeding may exhibit a range of plumage patterns, including black, blue, or splash. Variability in plumage coloration adds to the genetic complexity of breeding programs.

Traits of the Crested Blue Swedish Duck

Physical Characteristics: The Crested Blue Swedish duck is a medium-sized bird, with males typically weighing between 3 to 4 kg and females ranging from 2.5 to 3.5 kg. They are often likened to the body type of Cayugas and Orpingtons, although Swedish ducks should have shorter bodies with more width compared to these breeds.

Head and Plumage: These ducks possess medium, oval-shaped heads, and their plumage is characterized by a consistent blue slate color with darker lacing around the border of each feather. Drakes typically exhibit darker plumage compared to females.

Distinctive Features: One distinguishing feature of the Crested Blue Swedish duck is the white, heart-shaped bib found on the breast, extending up the front of the neck towards the mandible of the bird. This feature sets it apart from the Pomeranian Duck, particularly due to its white primaries.

Genetic Basis of Coloration: The blue coloration of the Crested Blue Swedish duck is attributed to heterozygosity in a dilution gene, contributing to its striking appearance.

Reproductive Traits:

  • Incubation Period: Eggs laid by Crested Blue Swedish ducks require an incubation period of 28 days.
  • Egg Characteristics: Most eggs are white, occasionally displaying a blue or gray tint.
  • Egg Production: These ducks have moderate egg-laying capabilities, producing approximately 100 to 130 eggs per year. Fitness – Meditation – Diet – Weight Loss – Healthy Living – Yoga

Weight: The average weights for Crested Blue Swedish ducks are:

  • Drakes: 7 lbs
  • Hens: 6 lbs


The Crested Blue Swedish duck possesses distinctive physical characteristics, including its medium size, unique plumage coloration, and the presence of a white bib on the breast. Its genetic basis for coloration contributes to its striking appearance, making it a notable breed within the duck community. Additionally, its moderate egg-laying capabilities and moderate size make it a valuable breed for both practical and ornamental purposes.
