Fertilized looking eggs but no roosters?

[Nora1923]

I asked a similar question in some Facebook groups and after posting pictures of my 10 chickens(now 9 due to a loss on Friday), I'm fairly certain I DO NOT have a rooster. My question is this. Probably 50% of the eggs I crack open look fertilized to me. Does this just happen? Does the disc just look different with each egg? I will post a picture of the eggs I cracked open today.

Those are fertile not fertilized.

I don’t see a bullseye/donut, so not fertilized i would guess.

To clarify, the white thin ring, I guess it looks like a ring you would wear, outside the solid white disc, is not considered a bullseye then? I'm just trying to educate myself better. Is the bullseye I read everywhere completely contained in the original white disc? I guess I assumed the white ring outside the original white spot was what everyone was referring to as the bullseye. I'm glad I asked this for the day I do get a rooster and decide to try hatching some eggs.

Can you post pics of all of your birds? It doesn't look fertile to me, but the ring thing on that one is confusing because it almost does look fertile.

I don't have great pictures of them, but I have posted some that I do have. I get a lot of eggs that have that ring around the white dot, but I also have about the same amount that is just the white dot.

Pretty birds! Yeah, they're definitely all hens. I think its just the way the yolk look on those. Fertile ones almost always have a smaller ring unless they've started developing for a day or so.

They do not look fertile to me.

@aart ?

Here is a picture of a fertile egg:

You can see the small bullseye formed in the yolk. I do see the ring you're taking about, but it's much too big. I'm not sure what it's called or if it has a name? Someone else might know.

I've read that parthenogenesis is possible in chickens eggs, however.

Your hen is fertile. You’d need a rooster for it to be fertilized.
