Question:
What part of the egg is the bird? Is it the yellow or the white?


Replies:
Neither. The zygote, which becomes the embryo, begins development on the surface of the yolk (yellow), which is the main energy source for the developing embryo. The albumen (white) provides a protective, cushioned surrounding for the embryo, and is also used up during development. Some of the yolk may be retained within the abdomen of the chick when it hatches.
