Fertilised egg?

[Jennyhen890]

Hi everyone, wasn’t sure where to put this one so admin can you please move if there’s a more appropriate area for this post.

Are these eggs fertilised? They look like bullseyes to me but just wanted to double check with you all. And yes I do have cockerels but they’ve not been together for a few weeks however I’ve read that hens can store the semen for a few months? Thanks in advance

It's very common for eggs to be fertile a few weeks up to even a month after a rooster has been removed. I've never heard or read any studies YET showing longer than that. Nor have I experienced eggs being fertile past that point through incubation practices.

Worth noting that in poultry, a hen may produce self fertilized eggs called parthenogenises. These eggs may even begin to develop embryos during incubation. Few will actually make it all the way to hatch, and those that do are usually male.

On the flip side of hens storing sperm, they can also reject it if they've been mated by an unwelcome suitor!

Thank you for your reply and sorry I’ve taken so long to reply! That is so interesting that hens can produce self fertilised eggs, I was amazed to learn that they could store the semen too. They really are fascinating.
