Why did chicken skin turn black when boiled?

Chicken skin can turn black when boiled due to a few reasons, such as the presence of certain pigments in the skin or the reaction of amino acids and sugars during cooking. If the chicken skin is exposed to high temperatures or has residual blood or dark meat, it may also darken. Additionally, any pre-seasoning or marinating with dark spices can contribute to the discoloration. It's important to ensure the chicken is fresh and handled properly to avoid any undesirable changes in color.
