is this egg possibly fertilized

I was making some breakfast for dinner and noticed one of the eggs looked different. We have a 26 week old silkie that's very passive that hasn't started laying yet and has not crowed so we are unsure if they are male or female.

This has a good picture of a fertile one. If it's fertile it should have a larger white ring around the white spot (germinal disc) Also see the thread below for another picture.

Your picture isn't super clear so it's hard to tell. But pretty dark egg yolks. Your girls are eating good.
