What part of an egg is the chicken and what other for?

This is a bit of a trick question! Here's why:

* The chicken comes *from* the egg, not *in* the egg. The egg is the container that holds the fertilized egg that develops into a chicken.

* The egg itself is meant for reproduction. The yolk contains the nutrients the developing chick needs, and the white (albumen) provides protection and moisture.

So, there isn't a part of the egg that is specifically "for the chicken." The entire egg is a package designed to support the development of a new chick.
