The Australorp is an Australian breed of dual-purpose utility chicken. It derives from the British Black Orpington, and was selectively bred for egg-laying performance; some hens lay more than 300 eggs per year. It achieved world-wide popularity in the 1920s after the breed broke numerous world records for number of eggs laid and has been a popular breed in the western world since. It is one of eight poultry breeds created in Australia and recognised by the Australian Poultry Standards. The original plumage colour is black, which is the only colour recognised in the United States of America, but blue and white are also recognised in Australia and the Poultry Club South Africa recognises buff, splash, wheaten laced and golden in addition.
