Ayam Cemani is a breed of chicken that is entirely black. Even its internal organs are black! ‘Ayam’ means ‘chicken’ in Indonesian and ‘Cemani’ translates to ‘completely black’ in Javanese. Ayam Cemani gets its black colouring from a generic trait known as ‘fibromelanosis’, that promotes the proliferation of black pigment cells. The breed, that originated from Java in Indonesia, is so exotic that it is referred to as the “Lamborghini of poultry”. They are one of the most expensive chickens in the world with a single bird costing up to $2,500. The hens lay cream-coloured eggs — the only part of the chicken that is not black.
