Oh, so Dunlap was wrong! Maybe @Papa John59 just won't add these "facts"?There are more "hen feathers" around the world : I don't know if the Vorwerk chickens exist in the States but we have them here in the Netherlands and they are hen feathered too. "Goldvogel" is the nickname of the Vorwerk grouse in Germany, the country of origin.
p.s.: found in article Vorwerk
The Golden Lakenvelder, a plumage variety, is a separate breed from the Vorwerk. Breeds used to create the Vorwerk included the Lakenvelder, Buff Orpington, Buff Sussex and Andalusian. By 1913, the Vorwerk was standardised, however, it never really gained widespread use, and is rare or non-existent outside Continental Europe.
Sorry about the incorrect information, everyone!
