Why is there an umbilical cord in an egg if it is unfertilized?

You must mean that stringy white stuff beside the yolk of an egg. That's not an umbilical cord. What you see is called the chalazae. Chalazae are strong protein strands designed to hold the yolk of the egg centered in the albumen (egg white). The chalazae in a real fresh egg are quite noticeable. They shrink or disappear as the egg ages in the shell. There is no umbilical need for avians (birds) since they are ovipositors. Egg layers have no need for umbilical cords as development takes place in a separate closed environment from the mother.

the chickens that i have dont. When a chick grows in an egg it does have an umbilical cord connecting it to the yolk to give it nourishment while it grows.
