Is this the beginning of a double yoker?

[Wease79]

My son went to make eggs this morning and one of the eggs had this in it? Its a little hard, didn't pop like a normal yoke. Anyone know what it might be?

Looks like an extra yolk was prematurely released. Not sure what to call it though; it is a double yolker, just not the normal kind.

It’s a mother yolk and a child yolk, they just go lost on their way to the egg park.

It's a double yolker, just one of the yolks is immature.
