Ayam Cemani is an uncommon and relatively modern breed of chicken from Indonesia. Their beaks and tongues, black combs and wattles, and even their meat, bones, and organs appear black. The birds’ black color occurs as a result of excess pigmentation of the tissues, caused by a genetic condition known as fibromelanosis. This gene is also found in some other black fowl breeds. The roosters weigh 2.0–2.5 kg and the hens 1.5–2.0 kg. The hens lay cream-colored eggs
