Looks like it to me but I'm not an expert... just a reader lol
I read somewhere that a fertile one will look like a tiny white target (a circle with rings) and an infertile one will just be a white? Not sure if I got that mixed up or not.
I think (and i could absolutely be wrong) that the ones with the little white spot on the yolk are fertile. That's a little zygote!
But it's still a little early to tell for most of them.
