What Is the Crested Duck?

Marlene Garcia

Domestic ducks called crested ducks descend from the mallard and feature a mutated gene that causes feathers to sprout from the top of their heads. The crest represents a deformity in the skull where a lump of fat protrudes through an opening in the bone. Feathers sprout from this tissue in varying amounts, which might range from a few wisps to a full crest that resembles a powder puff. Two main types of crested duck are the black and the white varieties, but cross-breeding produces gray and other colors.

Breeding a crested duck might be difficult because the gene responsible for the deformity causes about one-fourth of eggs to die before hatching if both parents carry the gene. Another 25 percent of ducklings might die after hatching because their brains are exposed. If only one parent carries the mutated gene, half of the ducklings that survive will be crested. Eggs hatch in 28 days.

The crested duck originated in Great Britain and has existed for thousands of years. It can be bred with any other domestic duck, except the Muscovy. In some parts of the world, these waterfowl are bred for exhibition, with large, symmetrical crests considered more desirable. Some people raise these fast-growing ducks for eggs or meat, while others keep them as pets.

The practice of breeding the crested duck for show might be banned in some regions because studies show coordination problems in this species. One study showed the size and location of fatty lumps creates smaller brains and olfactory openings in offspring. The number of feathers in the crest has no bearing on coordination limitations.

Some crested ducks cannot get up if they fall onto their backs. They might tumble down when walking or walk with a distinct gait indicative of coordination problems. One research study developed a test to identify birds with these defects so breeders can begin eliminating them through selective breeding. People buying crested ducks might use the test to identify healthy stock for the best breeding.

Scientists found some crested ducks needed more than a minute to flip onto their feet after being placed on their backs. These ducks had more fatty tissue in their craniums. Birds intended for breeding should right themselves within one or two seconds, researchers concluded.

Frequently Asked Questions

What is a Crested Duck?

A Crested Duck is a domesticated breed known for the distinctive tuft of feathers on its head, which is caused by a genetic mutation. This ornamental breed is primarily kept for exhibition, though it can also serve as a source of eggs and meat. Despite their unique appearance, they share many common duck behaviors and care requirements.

How does a duck get a crest?

The crest on a Crested Duck is the result of a genetic mutation affecting the skull's bone structure, which allows a clump of feathers to protrude through a gap. This trait is heritable, but it's linked to a lethal allele that can cause embryonic death if inherited from both parents, according to genetic studies on poultry.

Are Crested Ducks good layers?

Crested Ducks are moderate egg layers, typically producing about 100 to 130 eggs per year. While they are not the most prolific layers compared to other duck breeds, their eggs are well-regarded for their size and quality. They can be a charming addition to a backyard flock for those interested in both aesthetics and egg production.

Can Crested Ducks fly?

Like many domesticated duck breeds, Crested Ducks are generally too heavy to achieve sustained flight. Their body structure is more suited to life on the water and ground. While they may be capable of short bursts of flight or fluttering, they do not migrate and are considered flightless in practical terms.

What are the care requirements for Crested Ducks?

Crested Ducks require similar care to other domestic duck breeds. They need access to clean water for swimming and drinking, a balanced diet, and a safe, predator-proof enclosure. Regular health checks are important, especially for the crest, which can be prone to infection if not kept clean. They also need social interaction, either with humans or other ducks.

Is the Crested Duck suitable for first-time duck owners?

Crested Ducks can be suitable for first-time duck owners, but it's important to be aware of the special attention their crests require. Prospective owners should educate themselves on proper duck care, including nutrition, housing, and health management. With the right preparation, these ducks can be a delightful and rewarding addition to a new aviculturist's home.
