Barnevelder

It resulted from cross-breeding between local Dutch chickens and various "Shanghai" birds imported from Asia to Europe in the later part of the nineteenth century; these may have been of Brahma, Cochin or Croad Langshan type.

The hens are good layers of large brown eggs and, unlike some other breeds, continue to lay well during winter.
