What color of eggs do white chickens come from?

The White Leghorn, or one of its many crosses, will normally come from a white egg, but that doesn't mean white chickens only come from white eggs, nor that white eggs only produce white chicks. White Silkies come from beige or pink eggs. White Easter Eggers might come from blue, green, pink or dark brown eggs. I've had several white, bearded chickens come from olive colored eggs.

The original color of a chicken egg is blue. Naturally occurring genetic mutation has eliminated the blue color (white egg) or added brown (green, beige, pinks, chocolate, speckled, brown). It's just the color of the shell and generally has no connection with the coloration of the bird other than some breeds consistently lay a certain color of egg - again back to genetics.
