fertilized eggs?

[kychilds]

my leghorn chickens are about 19 weeks old and we just noticed they were laying about 2 days ago. we can't tell the difference between the roosters and hens right now but i read online today that if there is a bullseye lookin dot in the yolk that means the egg has been fertilized. i was wondering if anybody could verify this with the picture that i provided??
