Egg - half white/half dark

[bellyache]

If an egg is laid and one half of the egg is dark and the other half is white does that mean anything?
i have tried to take a pic but they not coming out clear enough. basically exactly half of the egg is white and other half is dark. mother is a golden and father is either a black wildtype or a lucky.

Albino females lay all-white eggs, are you sure it was a gold?

All other eggs start out back on one side and white on the other - the dark side is the embryo and the white is the yolk.
