Guinea/chicken egg cross?!

[AMoritz]

Ok so...I have 6 cinnimon queen hens and 2 mated pair guineas. It used to be 2 mated pair guinea and a lone female but last week she got taken by a fox .

In any case, I had to move the eggs my broody was sitting on because she was breaking em.
So as I'm putting the rest of the eggs in the incubator with the others I already had I come across this chicken egg...

Is this ACTUALLY growing a baby?!?!

that’s ok. Do you see veins?

I can't tell, one side of the eggs is darker then the other, I can see the air cell, or separation in it like you see in the first pic. But if this egg is viable it should be around day 18, which has me wondering if it died off. I didn't think there would be an air cell at all being it's a chicken egg with no roosters. The only option if it was fertile and died off after it started is that the father is one of my male guineas.....

Oh it’d be almost black inside if it’s that far along. Air cells are in every egg, not just fertile ones size increases as moisture is lost. New fresh eggs have tiny/sometimes nonexistent ACs. Older eggs are large.

Looks infertile. All eggs have air cells.

Awesome, ty! Now I can throw this thing away, which means one less egg to hatch. 65 eggs is still gonna be a lot

May be fertile.

May be fertile.

It doesn't stink at all, should I just keep it for awhile longer and see what happens? It should be around day 18 I believe right now...
