Why did your boiled chicken turn grey?

Boiled chicken can turn grey due to several reasons, primarily related to the cooking process. If the chicken is not cooked at a high enough temperature or is boiled for too long, it may lose its natural color and become grey. Additionally, if the chicken was previously frozen, ice crystals can form and affect its appearance when cooked. Lastly, the presence of certain minerals in water, such as iron, can also contribute to the grey color.
