Difference of fertile yolk and non fertile yolk. Dh cracked a egg today and it had 3 small brownish spots. He ate it anyway and he said it tasted fine.

Egg spots occaisionally happen and there is no problem with eating the eggs.

Maybe this link will work to show the difference between fertile and non fertile egg

Remember that heat is needed for the embryo in a fertile egg to develop....so if you refrigerate your eggs...it would be very difficult to see any difference.
