The Ayam Cemani is a rare breed of chicken from Indonesia. They have a dominant gene that causes hyperpigmentation (fibromelanosis), making the chicken mostly black, including feathers, beak, and internal organs. The Cemani is a very popular gamecock for cockfighting in Bali because their thighs have much more muscle compared to other chickens, which leads to them being much faster.^[1]
