THIS CHICKEN BREED IS RARE. Bohuslän-Dals svarthöna is a breed of Swedish black domestic chicken. It is believed that the chickens were first brought to Norway in the 17th century by sailors from Mozambique. In the mid-19th century, they started to appear in the Swedish Bohuslän Dalsland region, where they were mixed with local chicken breeds, and nowadays we have Swedish black chicken as a result – a distinct breed of small chicken with completely black skin.
