What’s going on in this egg?

[Knighstar679]

So I have been running a chicken experiment for my friend to see if they have a rooster hidden in their mists. I happened to crack open one of the ones that looked off to me and this is what I found. First the egg yolk popped when I opened the egg on its own. Second there was something solid in the egg but I don’t know what it is. ( it’s the brown thing about the middle)I would love help to understand this yolk. Thanks

It doesn't look like a developing embryo. I have got those in infertile eggs, usually its something the chicken intakes when eating or depends on the hen's diet.

It's called a meat spot or blood spot depending on whether it's in the white or yolk and has NO relevance to fertility.

Have your friend post pics... we are pretty good at identifying cockerels.

Had that egg been incubated during your experiment? Here is example of a non incubated fertile egg verses non fertile...

You are mistaken about it being something the chicken has eaten. It is caused by... quote form www.incredibleedibleegg.org

"These tiny spots do not indicate a fertilized egg. Instead, they are caused by the rupture of a blood vessel on the yolk surface during formation of the egg or by a similar accident in the wall of the oviduct."

I didn't say they indicate fertilized eggs, I said I have seen them in infertile eggs. I just wasn't sure at first it was a meat spot since they always occur in my hens eggs a lot for some reason.

This egg was on day six of incubation. I was pretty sure it wasn’t fertile. But the hard brown thing attached to the yolk was eye rising. I will see if I can find a pic of the bird in question.

Ok here is the suspect
They have been calling him Sly. I don’t know anything about chickens other than they are tasty and cute as chicks.

Sorry. I got that part. I meant that you were mistaken about the meat spot being caused by something the hen had eaten.

Did you see what causes them? It says a ruptured blood vessel or other piece of organ tissue sloughing off.

Yes, I see them in my non fertile eggs sometimes too. It happens.

Sly will never fertilize an egg in her life.

But she should lay some.

She looks like a production Red to me. A boy that big and red would surely be sporting some pointy saddle feathers by now. She has a lovely "hen bump"... and not a single male feather to speak of.

That being said... I DID have a production red pullet that insisted on mounting some of the subordinate gals. She is at a new home. She was lovely to humans and laid beautiful eggs. But...

I don't consider candling my strong suit.. but I agree with your assessment.
