are my hens' eggs fertilized?

[smoon]

My first chickens started laying a month ago. I have ten standard sized and three silkies. One of my silkies turned out to be a rooster and I am wondering if he is actually mating with my standard sized hens (barred rocks). He's much smaller and I've never seen him mate with them. In fact the hens pick on him! I'm wondering if someone can tell me if these eggs are fertilized just by looking at the yolks.

I see no indication that they are fertilized.

It almost looks like there are bull's eyes to me. It's hard to tell for sure, though. Here is a link with some pretty good pictures that might be able to help you tell for sure: https://www.backyardchickens.com/t/16008/how-to-tell-a-fertile-vs-infertile-egg-pictures

They are fertilised if u aren't to sure let the egg sit for three days then crack it. The bullseye will be larger and should have veins developing. If u have a hen who's laying a roo who of breeding age u gonna have fertile eggs.i have yet to catch my chickens mating and have fertile eggs and let her hatch them and am letting her lay right now to hatch more.

You won't get veins until egg has been at 100F for a few days.
