What color are white ducks when they are babies?

White ducks start out a different color when they first hatch from their eggs. Newly hatched white ducklings are typically yellow or gray in coloration, not white. The yellow or gray down helps camouflage the ducklings while they are vulnerable in the first few weeks of life. White ducks do not gain their distinctive white plumage until they are 4-6 weeks old.

Why are white ducklings born yellow or gray?

White ducklings hatch with yellow or gray down feathers to help protect them from predators. The light coloration serves as camouflage, allowing the ducklings to blend in with their surroundings like sand or dry grass. This helps hide them from predators like birds of prey when they are newly hatched and most vulnerable. Once the ducklings mature and grow their adult feathers around 4-6 weeks old, their color changes to white.

4-6 weeks White adult plumage

Some of the most common types of white ducks include Pekin, Aylesbury, and Rouen ducks. All of these duck breeds start out yellow or gray before becoming gleaming white ducks as adults. The temporary darker down helps conceal them while they are small and vulnerable to various predators.

What causes the color change in white ducks?

White ducks undergo a dramatic color change from yellow or gray to white as a result of genetic factors and feather maturation. All birds hatch with some form of juvenile plumage, which serves as camouflage early in life when they are most vulnerable. In the case of white ducks, their down feathers are a duller gray or yellow rather than pure white.

As the ducklings grow over the first few weeks of life, their juvenile down is gradually replaced by contour feathers. These feathers develop due to genetic factors that cause the ducklings to produce white feathers. By around 4-6 weeks old, the contour feathers have fully replaced the original down, resulting in the ducklings’ mature white plumage.

Do all white ducks change colors?

Yes, all varieties of white domestic ducks undergo a color change from their original dull down to pristine white feathers. This includes:

  • Pekin ducks – The most popular white duck breed. They have yellow down at hatching that changes to white.
  • Aylesbury ducks – A British duck breed with pale gray down that turns white.
  • Rouen ducks – Originating in France, they are born with dark gray down before becoming white.
  • Saxony ducks – German heritage ducks that start gray and end up white.
  • Silver Appleyard ducks – British ducks with grayish brown down changing to white.

Even white Muscovy ducks, which are technically a separate duck species from the breeds above, start out yellow before becoming white. No matter the specific breed, all white domestic ducks go through a multi-week color change starting at hatching.

When do white ducklings gain their adult coloration?

White ducks transition from their yellow or gray juvenile plumage to white adult feathers between 4 and 6 weeks of age. The exact timing depends on the individual duckling and breed. Some ducklings start growing white feathers as early as 3 weeks old, while others may take up to 7 weeks to complete the color change. On average though, most white ducks achieve their mature white plumage right around 1 month old.


In summary, white ducks are not actually white when they first hatch! Brand new white ducklings have yellow or gray down feathers that help camouflage them. Around 4-6 weeks of age, they transition to their mature white coloration due to genetic factors and the growth of contour feathers. This color change is a normal part of development for Pekins, Aylesburys, Rouens, and all other white domestic duck breeds.
