Think I've got a rotten egg 2nd opinions?

[Channel WHEN]

Hello! Long time lurker here. Recently had my 1st chicken go broody ( I've only had chickens for 2 years) I candled all the eggs today while mommy was on her "break". I threw out 1 blood ring and 1 clear but then came across this egg and wasn't so sure. I think its a quitter thats gone rotten but don't want to toss anyone out until I'm sure. Any help or advice is appreciated.

I'd mark it and check in a couple of days.

For a bit more information, I discovered her nest in my garden and then moved her the night of the 17th. I stuck an egg layed that same afternoon by an ee just to try and judge how far along all the other eggs are.

And here is the egg that seems the farthest along.

The egg I'm suspicious about in the opening post doesn't have any veins I can see and is still were as in almost all the other eggs I see dancers.( practically had a ballet going earlier )
I will certainly leave it another couple of days and check it.( I know that it's egg #14)
Here's a picture of mom and dad just cuz. Pretty certain dad is an ee.

I think you should toss it. If it was fertile to egg would develope veins before even starting the growth of the chick. It must just be a rotten yolk your looking at.

No question about those two eggs.

Toss it. You don't want to contaminate the ones that are developing, and that one is definitely not.

Thanks for all the input and advice. I'll check #14 again tomorrow when mom is on break just to double check. I'd really hate to get rid of an egg that had a chance (I want to be really sure!) but definitely don't want to risk all the other eggs as a result.
