Candling Guinea Eggs.

[morninggloryhatchery]

Hi!
So today i candled my guinea eggs i put in the bator 7 days ago. So far on 13 i see veins and the embryo. On two of the eggs there is a cloudy spot in the center and the other eggs looks clear to me. Does this sound normal? Any tips will be welcome.

Don't know much about the Cloudy one but i do know that the clear one is probably infertile because by the time its 7 days you should be able to see veins.
