The Ayam Cemani chicken is a rare breed from Indonesia
The black coloration of the Ayam Cemani is caused by a genetic condition known as fibromelanosis, resulting in hyperpigmentation. This condition leads to an overaccumulation of melanin pigment in the body's tissues. While their bones are indeed black, contrary to popular belief, their blood is not; it is red due to its hemoglobin content, just like all other chickens.
In their native Indonesia, the Ayam Cemani holds cultural and spiritual significance. They are believed to possess mystical powers and are used in various spiritual practices, ceremonies, and traditional healing methods. In Bali, these chickens are also used for cockfighting, an ancient cultural tradition regarded as a religious ritual.
Outside of Indonesia, the Ayam Cemani is sought-after for its rarity and exotic appearance. They are known for their moderate egg-laying abilities, producing cream-colored or tinted eggs, and their meat, which is higher in protein and lower in fat than other chicken breeds. The breed is also known for its calm and docile temperament, making them excellent pets for enthusiasts.
Today, the Ayam Cemani remains a rare breed, with numbers below 3500 worldwide. While their prices have dropped since their introduction to Western markets, they are still challenging to find and often face issues with purity and coloration.

They are characterised by hyperpigmentation, caused by a dominant gene
The Ayam Cemani is a rare breed of chicken from Indonesia. They are characterised by hyperpigmentation, caused by a dominant gene known as fibromelanosis, which results in the chicken being mostly or entirely black. This includes the chicken's feathers, skin, beak, comb, wattles, tongue, meat, and internal organs. Even their bones are believed to be black, though this is not actually the case.
The name "Ayam Cemani" translates to "completely black chicken", aptly describing the breed's most notable feature. The breed was developed over centuries on the island of Java, where traditional breeding practices have been maintained for generations. While the Ayam Cemani may share some genetic ancestry with jungle fowl, they have been selectively bred for specific traits, including their unique all-black appearance.
The fibromelanosis gene causes an excess pigmentation of the tissues, resulting in the black coloration on both the inside and outside of the Ayam Cemani breed. This gene is found in several other chicken breeds, including the Kadakhnath in India, the Black H’Mong in Vietnam, and the Svart Höna from Sweden.
The Ayam Cemani is steeped in mysticism and is prized in its native land of Java for its magical blood and medicinal properties. They are believed to treat cardiovascular and respiratory disease and are used for ritual ceremonies. In Bali, these chickens are used for cockfighting due to their enhanced muscle mass, which makes them faster than other breeds.
In summary, the Ayam Cemani is characterised by hyperpigmentation caused by a dominant gene, resulting in their distinctive all-black appearance and cultural significance in their native land of Java, Indonesia.

This gene, fibromelanosis, is uncommon and results in black feathers, beak, and internal organs
The Ayam Cemani is a rare breed of chicken from Indonesia. They are known for their distinctive appearance, with entirely black feathers, skin, and internal organs. This unique coloration is the result of a gene called fibromelanosis, which causes hyperpigmentation and an excess of melanin in the skin and connective tissues.
Also known as the "Lamborghini of poultry", the Ayam Cemani has a long history steeped in mysticism and folklore. In their native land of Java, these chickens are prized for their magical blood and meat, which is believed to possess medicinal powers. The breed is thought to have descended from wild jungle fowl and was once reserved for royal families in Java, adding to its air of exclusivity.
The gene responsible for the Ayam Cemani's black colouring, fibromelanosis, is relatively uncommon and results in black feathers, beak, and internal organs. This genetic trait leads to an excess of pigmentation in the tissues, creating the distinctive black appearance that has made the breed so sought-after.
The fibromelanistic gene, as it is also known, causes an increase in melanin production, resulting in black pigment accumulating in the skin and connective tissues. This gene is not limited to Ayam Cemani chickens but can also be found in some other chicken breeds, such as the Silkie, although it is quite rare.
The black coloration of the Ayam Cemani extends beyond just their feathers and beak. Their tongues, combs, wattles, meat, and even their internal organs and bones are also black. This uniformity of colour is so prized that the Ayam Cemani Breeders Association has established strict breed standards, allowing only grey and black colours in the mouth and no other feather colour besides black.
