The jet-black Ayam Cemani chicken is a unique breed that originated from the island of Java, Indonesia. Florida-based breeder Paul Bradshaw started selling them for $2,500 (£1,700) each in 2013.

The all-black chickens, nicknamed the ‘Lamborghini of Poultry’, were his “most requested bird ever”. The chicken is named after a village (Cemani) in central Java.

Their beak and tongue, black comb and wattles; even their meat, bones and organs appear black. The blood of the Ayam Cemani, however, is normally coloured.

The birds’ black colour occurs as a result of excess pigmentation of the tissues, caused by a genetic condition known as fibromelanosis and is also characteristic of Chinese Silkies, a black chicken treasured across China.
