KFC chicken is not considered kosher. This is because KFC does not adhere to the dietary laws and regulations of the Jewish religion, which govern what foods can and cannot be consumed by observant Jews. KFC chicken's preparation and cooking process involves various ingredients, including seasoning and frying, which may not comply with the strict kosher dietary laws. Therefore, KFC chicken is not considered kosher and is unsuitable for consumption by those who observe kosher dietary restrictions.
