Is this egg infertile?

From what I hear, it's rare, but, yes, there is such thing as Pekin x Call cross.

Wow! I think I am going to try to hatch some my next go around. I never imagined that my tiny call would be successful in mating with my jumbo Pekin hens! You should have seen my face when I read that they were fertile... I think my jaw might still be on the floor!
