Need help identifying fertilized eggs

[ducaria]

I'm new to chickens and need some help identifying if these eggs are fertilized.

Before I make any guesses do you have a cock (rooster)? A hen can lay eggs without a rooster present.

Blastodisc are the infertile dots you see while the blastoderm is a bunch of concentric rings like a bullseye.

The top one, I can't tell but the bottom 2 definitely look fertile to me.

Yes I do have a rooster. Never seen them mate though. It's a unclear pics but the lower one looks like a bullseye but not sure.

The top one, I can't tell but the bottom 2 defiantly look fertile to me.

Thanks. Yeah top I didnt bother to find the embryo because I broke the yoke.

If they weren't fertile, the blastodisc (sp?) would be the size of a pin head. The "bullseye" isn't always apparent but you can tell by the size of the blemish.

I see. Thanks for your help.
