Do I need to separate?

[Mimi13]

I did not take any pictures of the yolks, just remember thinking how strange. They were definitely fertile.

Or so I thought anyway.

There have been discussions about eggs that look fertile but are not...I can't remember what it's called...ah, googling close to spelling helped me find it.....parthenogenesis. Not sure if that totally correct tho.
@ChickenCanoe and/or @Ridgerunner probably know the details.

Parthenogenesis can occur and you can even get live hatches. It's mainly been documented in turkeys more than chickens. It's been years since I read about it about it and don't remember how it happens. It is kind of hereditary but even in flocks of turkeys bred for it the rate is pretty small. It doesn't just make the eggs look fertile, they actually are.

Mimi, I don't know if that caused some of your eggs to look fertile or not. There are probably other things that could cause them to look fertile. I put this down to you can never tell what will happen with living animals. When you make blanket statements about anything there can be exceptions.

Well, that’s an awfully big word to be used for a little bird, but, come to think of it, most chicken illnesses are HUGE words.

This morning when fixing breakfast, I scanned the eggs really well. I have attached several pics of the egg I think looks fertile. Then again, maybe it isn’t. But this egg looks like the others I am talking about when I say they appear fertile.

Well, @aart and @Ridgerunner, what is the verdict? Am I just seeing things or are my birds weird?

Boy that sure looks like the proverbial bullseye!

 

[Ridgerunner]

Looks like a bull's eye to me. Nice clear shot.

Looks like you have a rooster in hiding. That definitely looks like a bullseye.

I know, but my main cockerel has not been out with the flock at all since the beginning of December. I have a new to me cockerel that I let out with my flock for the first time last Monday. I have been noticing these “fertile” eggs for over a month now. This is indeed strange.

@Mimi’s 13 Can a visiting Roo get into your pen?

@Mimi’s 13 Can a visiting Roo get into your pen?

No. That would be impossible. There aren’t even any roosters within a couple of miles or more.

 

[Banditschickens]

Unless you got the rarest of hens.
That is also a rooster.

I apologize, @Pgrine, for hijacking your thread. However, all this is very interesting and has me wanting to do more investigation and I will begin a new thread to follow through. Thank you, everyone who has had input on this. Hopefully you will continue to help me figure out this mystery.

ETA - What section does this even need to go in?

That's ok. I don't mind at all.
