You can figure out the color of a chicken egg by looking at the chicken's earlobes. Yes, even though they don't have outer ears, chickens do have earlobes, and they vary in color, from white to much darker varieties. That's probably not that surprising, but the correlation between earlobe color and egg color certainly is. Chickens with white earlobes lay white eggs, while chickens with darker brown earlobes lay—you guessed it—brown eggs.
