Ayam Cemani is an uncommon and relatively modern breed of chicken originating in Indonesia. They have a dominant gene that causes hyperpigmentation (also termed as Fibromelanosis) leading to the skin, feathers and even the internal organs appearing dark black.

Etymology

Ayam means "chicken" in Indonesian and Cemani is "completely black" in Javanese.

Origin

The breed originated from the island of Java, Indonesia and was probably in use for centuries and used for religious and mystic rites. They were first described by Dutch colonial settlers.[1] It was first imported into Europe in 1998 by Dutch breeder Jan Steverink. Currently stocks are kept in the Netherlands, Germany, Slovakia and the Czech Republic. There are several varieties of the Ayam Cemani including the Swedish Black Chicken. It is thought that Ayam Cemani may also earlier have been brought to Europe by Dutch seamen who had numerous contacts in both Africa and Asia.[2]

Description

The birds are completely black: black plumage with a greenish shine, black legs and toe nails, black beak and tongue, black comb and wattles; even their meat, bones and organs appear black. The blood of the Ayam Cemani is normal (though it is remarkably dark).The birds' black colour occurs as a result of excess pigmentation of the tissues, caused by a genetic condition known as fibromelanosis.[3] This gene is also found in some other black fowl breeds.[4][5] The roosters weigh 2–2.5 kg and the hens from 1.5–2 kg. The hens lay cream-colored eggs with a slight pink tint, although they are poor setters and rarely hatch their own brood. Eggs weigh an average of 45 g.[6]

Individual birds in the United States of America have been priced at $2500.[7]
