Blastoderm or blastocyst? Help please

[DynesLady]

The last two eggs I cracked really caught my eye when I wasn't looking for anything--one dropped on the ground outside and gave me a double-take, and the other cracked for a recipe gave me the same double-take. My daughter and I have been examining fertile/infertile egg photos online and these two yolks really seem to have the "bullseye" appearance of a fertile egg. Here's the thing: we're rooster-less! They are free range on over and acre, though, and the neighborhood does have "feral" bantams. I have NEVER seen my flock close to the bantams, but if this is a fertile egg--I think I might have a secretive, promiscuous hen!

Please give your feedback.

It kind of looks like a blastoderm, not completely though. If you have a picture of another one that may help

Thank you, Poultry Parent. I do have a photo of the other egg (I dropped it outside), but it isn't as good. I'll post it anyway, though.

It's hard to tell with a not so perfect yolk, but it looks like blastoderm to me. A blastodisc is usually just a small irregular shaped white spot. That looks more round and definitely larger. I would lean toward the fertile side.

Vid say that they're probably fertile

They sure are getting a lot of votes for "fertile," though the consensus is primarily "unsure." If only one of my ladies would go broody and sit on them! In the meantime, eggs for eating are a-okay with us!
