Pic: One yolk, double fertilized?

Am I crazy or are their two circular areas here when there should only be one? Can a single yolk have two germ disks from the hen?!

Hmmm… interesting. I have never seen this before. I think that there is only one and the other one is just the way the yolk looks.
Anyway I wouldn‘t worry about it. I don’t see anything that is a problem.
