any advice - spotting the fert eggs?

[tara7815]

I have 2 broody hens. they are both snug in one nest box
We gave them some fertilized eggs day before yesterday.
But yesterday there were 2 extra eggs in there. I thought the ones we gave her were smaller than the ones she was laying so I thought it would be easy to know which ones we needed to pull out of the box (as they aren't fertilzed). So now I have 2 more eggs in there than I did before and I have no clue which ones to pull out. I meant to mark the fertilized eggs and I just spaced out.

Any suggestions?

With only one day between them, I'd say don't worry about it. Just mark them all now, so if the other hens keep laying on top of her, you'll know which ones to pull out.
