The Crested is a breed of domestic duck. It was probably brought to Europe from the East Indies by Dutch ships.[1]:413 It has its appearance because it is heterozygous for a genetic mutation causing a deformity of the skull.

History[edit]

The Crested probably originates in the East Indies, with subsequent development in Holland.[1]:413 Crested ducks are seen in seventeenth-century paintings such as those of Melchior d'Hondecoeter and Jan Steen. Paintings as old as 2000 years have depicted images of a bird, resembling a duck with an assortment of feathers on top of its skull.[5] In the United States the breed was described by D.J. Browne in 1853.[1]:413[6]:197 The white Crested was added to the American Standard of Perfection in 1874; the black variant was added in 1977.[2] The Crested was recognised in the United Kingdom in 1910.[1]:413 In the UK, as in several other European countries, any colour is permitted.[3]

The crest is large and well centered on top of the skull. They have long, slightly arched necks, medium length body, lots of depth and fullness through the breast.[7]

A bantam version of the breed, the Crested Miniature, was bred by John Hall and Roy Sutcliffe in the United Kingdom in the late twentieth century; it was recognised in 1997.[1]:415 The crested gene is very popular in Europe, resulting in crested versions of most breeds.[5] Though Cresteds can be good layers and strong roasting qualities, the main interest and demand for the breed is as pets and decorations. They are not a popular show breed due to challenges associated with the crest.[5]

Breeding[edit]

When two ducks heterozygous for the crested allele breed, their offspring are in the usual 1:2:1 ratio:

  • 25% are homozygous for the normal allele of this gene and so have no crest and if bred together their offspring will never have a crest.
  • 50% are heterozygous for this gene and hatch with a crest of varying sizes.
  • 25% are homozygous for the crested allele of this gene and die from exposed brain without hatching, as it is lethal in homozygous form.

The offspring of a duck with a crest and a duck with no crest are expected to be 50% with and 50% without a crest.
