Austrothrop Chicken: The Secret To Its Heritage

what chickens were bred to create the austrothorp chicken

The Austrolope chicken, also known as the Australorp, is an Australian breed of chicken that was selectively bred for egg-laying performance and size. The breed was launched internationally in the early 1920s and was created by crossbreeding Black Orpingtons with Rhode Island Reds, Minorca, White Leghorn, and Langshan chickens. The name Australorp is thought to be a combination of Australian and Black Orpington, as the breed originated from Black Orpingtons imported from England and was refined in Australia. The Australorp is known for its glossy black feathers, large size, and egg-laying abilities, with some hens laying up to 300 eggs per year.

Black Orpingtons

The Black Orpington is a breed of chicken created by William Cook in the 1880s. Cook, a resident of Orpington in Kent, England, set out to create a new utility chicken that was hardy in winter and good for both eggs and meat. To achieve this, he mated Black Minorca cocks with black Plymouth Rock hens, and then mated the black offspring from these birds with the Black Langshan. The result was a black fowl with a handsome appearance.

The Black Orpington is one of the largest of the Orpingtons and is known for its iridescent blues and greens, also known as Beetling. They are also one of the friendliest Orpington breeds and are excellent at spotting sky predators, alerting the rest of the flock to take cover. A healthy Black Orpington hen can lay 120-200 eggs per year and achieve a weight of 8-10 lbs, while a cock bird can achieve a weight of 10-12 lbs.

The breed was further developed by Joseph Partington and friends, who increased the bulk and feather of the Black Orpington to the standard we know today. The Orpington Club was formed in 1887, and the breed gained rapid popularity. However, it was not until 1900 that the black Orpington became a distinct kind.

The Black Orpington was later imported to Australia and crossbred with local birds to create the Australorp breed in the late 19th century. The Australorp was developed by Australian farmer William Edmund Roo, who aimed to improve the Orpington's egg-laying capacity and overall health. The Australorp gained international popularity in the early 1920s, attracting attention for its impressive egg-laying performance, with some hens laying more than 300 eggs per year.

Rhode Island Reds

The Rhode Island Red is an iconic American chicken breed that originated in Rhode Island and Massachusetts in the 1840s. It is the state bird of Rhode Island and is recognised as a distinct pure chicken breed. This breed is a cross between a Malay and a Brown Leghorn, which is where its characteristic deep red plumage comes from. The Rhode Island Red is a dual-purpose breed, providing both meat and eggs.

The Rhode Island Red was developed to be well-suited to the local climate and environment. Crossbreeding with the Orpington and other local breeds resulted in a sturdy, hardy bird capable of thriving on limited resources. The initial goal was to improve egg production and create a reliable meat source. Rhode Island Reds are good egg layers, producing light brown eggs. They are also known to be energetic, friendly, and dominant within a flock.

The colour of the plumage of the traditional Rhode Island Red ranges from a lustrous deep red to almost black, with a mostly black tail. The comb may be either single or rose-comb, and is a vivid red, as are the earlobes and wattles. The beak is a reddish horn colour, the eyes are reddish bay, and the feet and legs are yellow, often with some red on the toes and sides of the shanks. Rhode Island Reds are known to be hearty and do well in harsher environments, thriving in both cold and warm climates.

Minorca, White Leghorn, and Langshan chickens

The Austrothrop chicken was selectively bred from Minorca, White Leghorn, and Langshan chickens. The Minorca chicken is the largest breed in the Mediterranean class, with a carcass weight of 6.5-7.5 pounds. They were first imported to England in 1834 and then to America in 1884. Minorca chickens are imposing birds with large, beautiful, full tails and muscular legs. They are hardy and good at evading predators, but they are not suited for colder climates as they are prone to frostbite.

White Leghorn chickens are not mentioned in the sources provided, but Langshan chickens are described as a valuable general-purpose breed. They were first imported from China to England in 1872 by Major A.C. Croad, and they were later imported to America in 1878. There are several varieties of Langshan chickens, including the shorter-legged version that contributed to the creation of the Orpington chicken breed, the German Langshan with long legs and no feathering, and the Modern Langshan with tighter plumage and a slimmer breast.

The Austrothrop chicken, also known as the Australorp, was developed in Australia from imported Orpington chickens, which were originally bred in England. The name "Australorp" combines "Australia" with the suffix "orp" to denote the Orpington breed. The Australorp gained international popularity in the early 1920s due to its impressive egg-laying performance, with records being set for the number of eggs laid. The breed was recognised by the American Poultry Association in 1929 and has since spread worldwide, recognised in countries such as Australia, South Africa, and the United States.

Imported to Australia

The Australorp is a breed native to Australia, having been bred from the British Black Orpington chicken. The original stock used in the development of the Australorp was imported to Australia from England out of the Black Orpington yards of William Cook and Joseph Partington in the period from 1890 to the early 1900s. During this same period, Black Orpingtons in England were being refined for their meat qualities. However, the Australians immediately valued the breed for its egg-laying ability and continued to breed along the lines of the original type.

Local breeders used this stock together with out-crossings of Minorca, White Leghorn, and Langshan blood to improve the utility features of the imported Orpingtons. There are also reports of some Plymouth Rock blood being used. The resulting birds were known as Australian Black Orpingtons (Austral-orp). The name "Australorp" is a combination of two words: "Australia" and "Orpington," referring to the Orpington breed that was brought over from England to crossbreed with local birds.

The Australorp was developed in the late 19th century by Australian farmer William Edmund Roo, who began selecting from Orpington chickens to create a robust and productive bird. Roo's breeding program focused on selecting for desirable traits such as large egg size, high fertility rates, and resistance to disease. He also emphasised the importance of temperament, aiming to create birds that were calm and docile. By the early 20th century, the Australorp was officially recognised as a distinct breed, and it achieved worldwide popularity in the 1920s after breaking numerous world records for the number of eggs laid.

The Australorp is part of the 'English' class of chicken. The black-coloured Australorp is the most common and popular colour in Australia, though blue and white varieties are also recognised in the country. The breed is known for its impressive size and weight, making it one of the largest chicken breeds. It is a heavy breed that lays eggs productively, regardless of weather patterns or seasonal changes. Australorps are also known to be good nest sitters and mothers, making them one of the most popular large heritage utility breeds of chicken.

Bred for egg production

The Australorp chicken breed was developed in Australia in the early 20th century, specifically for egg production. The breed was derived from the British Black Orpington chicken, which was imported to Australia between 1890 and 1900. During this period, Black Orpingtons in England were being refined for their meat qualities. However, Australian breeders took a different approach, focusing on egg-laying performance without compromising size and meat quality.

The name "Australorp" is believed to have originated in the early 1920s, when the breed gained international recognition. Prior to this, the birds were known as "Australian Black Orpingtons" or "Australian Laying Orpingtons". The breed broke several world records for egg-laying during this decade, further cementing its reputation as an exceptional egg producer.

Between 1900 and 1922, five primary bloodlines of Australorps were developed: Graham, Burns, Christie, Bertelsmeier, and Drewitt. Breeders used different crosses with the imported Orpington chickens but maintained the general type originally released by William Cook. Notably, they also bred to eliminate broodiness, which contributed to the commercial success and establishment of Australorps as a distinct breed.

The Australorp chickens are known for their impressive egg-laying abilities, with some hens capable of producing more than 300 eggs per year. The eggs are light brown in colour, weighing approximately 55 grams each. The breed's productivity, combined with its dual-purpose utility as a source of meat, led to its worldwide popularity in the 1920s.

Today, Australorps remain a popular breed in Australia and beyond. They are recognised by the American Poultry Association (APA) and are known for their longevity, hardiness, and gentle temperament. The breed's heavy weight also makes it well-suited to withstand cold winter temperatures and hot weather conditions. Overall, Australorps have become an iconic Australian chicken breed, valued for their egg production, meat quality, and adaptability to various climates.
