Ayam Cemani is a rare breed of chicken that is completely black, including its organs, muscles, and bones.
Cemani, pronounced che-MA-ni in Indonesian and seh-MA-ni by many English speakers, comes from Sanskrit and means "jet black."
As a result of a condition called fibromelanosis, Cemani chickens have 10 times as much melanin as most chicken breeds.
While the price varies, a high-quality Ayam Cemani can sell for over $6,000, and a single egg can fetch as much as $16.
But what makes these chickens so special?
