Norwegian Jaerhons were developed in Norway and between the years of 1916 and 1973 was selectively bred for productivity of white eggs at a state-controlled breeding station in Jaeren. Jaerhon chicks have a gold head with a white spot on top. The back is brown mixed with gold, and they have two light gold streaks that run down the side of the back. They have single combs and clean, yellow legs and feet. Adults have silver barred plumage with a gold infusion that is very difficult to describe. Because of the action of the barred gene, the male plumage is lighter than that of the female.
