Icelandics. The ability to range was an important trait, in a country with long winters and little available homestead grain to feed a flock. The breed was isolated from the 9th Century to the past one. Ranging ability is strong in them as is flying ability, they normally seek the highest place in a barn or coop to roost. I dont know of another breed that flys as well or ranges as well. Check the thread here for accounts on this.
