Do chickens have belly buttons?

Belly buttons show where the umbilical cord attached to the baby. Umbilical cords attach a baby to the mother for nutrients and oxygen. Only babies that are in the uterus for development have this. Chickens hatch from eggs and therefore don't have a bellybutton. Mammals have belly buttons, other animals do not. read more
