Isbar, Silverudd Blue and the name confusion

The Isbar is a Swedish breed developed in the mid 1900s by Martin Silverudd, a breeder who created several laying breeds in Sweden. Many sellers use Isbar and Silverudd Blue for the same bird, which is why both pages exist. If you are buying, the name alone does not tell you much. Ask what the birds look like and what color eggs the hens lay.

What most Isbars look like today

Most birds sold as Isbars in the US come in blue, black and splash. Blue to blue matings give a mix of all three, since blue does not breed true. They are medium-sized, fairly light-bodied birds with single combs.

Eggs

Isbars are known for green-tinted eggs, from light mint green to deeper shades depending on the hen. They are good layers for a non-production breed.

The bar in the name

The ending follows the same naming style as British autosexing breeds like the Rhodebar and the Legbar, where chicks can be sexed by color at hatch. Some older sources describe the Isbar as autosexing. The blue, black and splash birds sold today are generally not sexed this way, so do not count on it unless the seller confirms it.

Living with them

Keepers describe them as active and friendly. They forage well and are cold-hardy, though single combs can get frostbite in very cold weather. They are not common, and most come from small breeders.
