There are only a few chicken breeds that have black or dark-colored skin. Some of these breeds are:
1. Silkie Chicken: This breed is known for its fluffy feathers, black skin, and striking blue earlobes.
2. Ayam Cemani Chicken: This is an Indonesian breed that is entirely black, including the skin, feathers, eyes, and comb.
3. Svart Hona Chicken: This is a Swedish breed that is entirely black with shimmering feathers and black skin.
4. Black Meat Chicken (also known as Kadaknath): This Indian breed has black feathers and black skin, and its meat and bones are also black.
These breeds are relatively rare and unique compared to conventional chicken breeds. It's worth noting that while the black skin of these breeds may seem unusual, it does not affect the taste or nutritional value of the chicken.
