Fertile Eggs?

[Its ME]

I cracked open 5 of my most recent duck eggs and I’m wondering which ones, if any, are fertile. Thanks!

Not sure about the dark one at the bottom left, or the very topmost one. The rest look fertile to me.

There's a lot of glare in your picture, but all eggs appear to have the 'bulls eye' indicating fertility.

I would have to agree, they all look fertile to me.

I can only tell fertility in the left, right and bottom right.
