Egg Integrity/safety
There is no conclusive reason to say about safe or not either way. 

When an egg is frozen, the yolk changes irreversibly. Even after thawing, its consistency is very different, much thicker than normal. 

On the other hand, it may never have been frozen, but have been contaminated by something instead. Or it may have been frozen first and contaminated afterwards. 

You cannot say what caused the visible, if it was freezing or microorganisms. So it is unsafe. As for there being something wrong, nobody can tell without a trip to the lab.
