Are these eggs fertilized?

[chickenlittle21]

Today is day 6 and I candled the eggs today for fun. I am not going to throw any eggs away until day 17 just to be sure.
Here are the pictures of the eggs, which ones look fertilized?

I can't see anything in #11 but all the rest look fertile to me!

They all look like they are developing to me

I think they’re all developing!! Nice job! As for #11, if you turn the colors down you can see some feint veining.
