Occasionally, a small blood spot will appear in an egg yolk. This actually indicates an extremely fresh egg. This does not indicate a fertile egg, but rather a ruptured capillary on the yolk surface during the egg formation. These eggs are safe to eat and the blood spot can be removed with a knife for better appearance.
