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

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.
