The Australorp is a chicken breed of Australian origin, developed as a utility breed with a focus on egg laying and is famous for laying 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 most popular colour of the breed 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.
The Sussex is a British breed of dual-purpose chicken, reared both for its meat and for its eggs. Eight colours are recognised for both standard-sized and bantam fowl. A breed association, the Sussex Breed Club, was organised in 1903.
The Plymouth Rock is an American breed of domestic chicken. It was first seen in Massachusetts in the nineteenth century and for much of the early twentieth century was the most widely kept chicken breed in the United States. It is a dual-purpose bird, raised both for its meat and for its brown eggs. It is resistant to cold, easy to manage, and a good sitter.
Hollands are a fairly rare breed of large chickens that are dual purpose and originate from America. They are hard to tell from Plymouth rocks and Dominiques, but can be recognized as the Plymouth Rock has colored feet and the Dominique has a rose comb.
The Campine is a breed of domestic chicken originating in the northern part of Belgium. It is named for the Campine region of north-eastern Belgium and south-eastern Netherlands. It was known there as the Kempisch Hoen.
The California Gray is an American breed of domestic chicken. It may be also known as the "production black".
The Rhode Island White is a breed of chicken originating in the U.S. state of Rhode Island. Despite their very similar names and shared place of origin, the Rhode Island White is a distinct breed from the Rhode Island Red. However, Rhode Island Reds and Whites can be bred together to create Red Sex-Link hybrid chickens, such as the ISA Brown. In Australia, the Rhode Island White is regarded as a color variety of the Rhode Island breed according to the Australian Poultry Standards.
The Java is a breed of chicken originating in the United States. Despite the breed's name, a reference to the island of Java, it was developed in the U.S. from chickens of unknown Asian extraction. It is one of the oldest American chickens, forming the basis for many other breeds, but is critically endangered today. Javas are large birds with a sturdy appearance. They are hardy, and are well-suited for both meat and egg production, especially by small-scale farms, homesteads, and backyard keepers.
Urban keeping of chickens as pets, for eggs, meat, or for eating pests is popular in urban and suburban areas. Some people sell the eggs for side income.
Delayed-feathering in chickens is a genetically determined delay in the first weeks of feather growing, which occurs normally among the chicks of many chicken breeds and no longer manifests itself once the chicken completes adult plumage.
Solid black plumage color refers to a plumage pattern in chickens characterized by a uniform, black color across all feathers. There are chicken breeds where the typical plumage color is black, such as Australorp, Sumatra, White-Faced Black Spanish, Jersey Giant and others. And there are many other breeds having different color varieties, which also have an extended black variety, such as Leghorn, Minorca, Wyandotte, Orpington, Langshan and others.
In poultry standards, solid white is coloration of plumage in chickens characterized by a uniform pure white color across all feathers, which is not generally associated with depigmentation in any other part of the body.
Chick sexing is the method of distinguishing the sex of chickens and other hatchlings, usually by a trained person called a chick sexer or chicken sexer. Chicken sexing is practiced mostly by large commercial hatcheries to separate female chicks or "pullets" from the males or "cockerels". The females and a limited number of males kept for meat production are then put on different feeding programs appropriate for their commercial roles.
The Bielefelder Kennhuhn or Bielefelder is a German breed of domestic chicken. It was developed in the area of Bielefeld in the 1970s by Gerd Roth, who cross-bred birds of Malines and Welsumer stock with American Barred Rocks to create the breed. Like other breeds with Barred Rock parentage, it is auto-sexing – chicks of different sexes can be distinguished by their colour. There is a bantam version, the Bielefelder Zwerg-Kennhuhn.
Auto-sexing breeds of poultry are those in which the sex of newly-hatched chicks can be determined from the colour and markings of the down. Some breeds of chicken, of goose and of domestic pigeon have this characteristic. The idea of such a breed is due to Reginald Punnett, who created the first auto-sexing chicken breed, the Cambar, at the Genetical Institute in Cambridge in 1928.
Slovenian Barred Hen is a traditional breed of domestic chicken, originating in Slovenia. This breed was developed on the Biotechnical Faculty of University of Ljubljana some decades ago. Animals of the Slovenian Barred Hen are barred black and white layer hens, used primarily for production of commercial crossbreeds sold under the trademark Prelux.
Slovenian Brown Hen is a traditional breed of domestic chicken, originating in Slovenia. It was developed at the end of the 20th century at the Biotechnical Faculty of University of Ljubljana. Animals of this breed are brown coloured layer hens that are also used as parents for commercial crossbreeds sold under the trademark Prelux.
Slovenian Silver Hen is a traditional breed of domestic chicken, originating in Slovenia. The breed, that was developed some centuries ago on the Biotechnical Faculty of University of Ljubljana, is characterised by typical white coloured layer hens, used primarily for production of commercial crossbreeds sold under the trademark Prelux.
Prelux are commercial chicken crossbreeds of the Slovenian origin, that are being sold under the eponymous trademark by the Biotechnical Faculty of University of Ljubljana. The name is an abbreviation for the Slovenian phrase prevojski luxuriranci, with a word luxuriranci referring to luxuriance (heterosis) or outbreeding enhancement of hybrid offspring, and adjective prevojski referring to the Slovenian settlement Prevoje, where selective breeding was once performed. This name was given to quality layer hens, that are being obtained by crossbreeding three Slovenian traditional breeds of layer hens; Slovenian Barred, Slovenian Brown and Slovenian Silver Hen. The most known and best-selling layer hens of the trademark Prelux are Prelux-Č, Prelux-G and Prelux-R. A part of the selection is also a meat type chicken (broiler), Prelux-BRO.
Golden Comet is a cross bred and sex linked chicken gotten from the crossbreeding of a female White Rock or Rhode Island White and a male New Hampshire Red chicken.
