Are my eggs fertile

[Dwel1234]

Hello everyone
I have 2 cockerels in my flock who seem to now be at the top of the pecking order (they were both young when we got them and so we’re being hen pecked)
I have seen both cockerels trying to mount the hens but am unsure yet if the eggs are fertile. I have taken some pictures below, could anybody help me to identify if they are fertile or not?

The one in the last picture is, not sure about the others.

You can tell when it looks like a bulls eye. Ring around the dot. This one is not.

Thank you for the reply, so would you say 1&4 potentially are fertile?

You are Welcome! Looks like it 1 @ 4 i say yes! 2 could be? the dot is huge, does it have a ring?

This egg would hatch.

FYI, this is the Buy-Sell-Trade section. you may want to ask a mod to move this to incubation and hatching.
