Help... 2 empty eggs

[Paddlehands]

This morning i found 2 cracked emtied eggs 8 meters uphill from where my ducks are nesting.

What could have done that

Photos? Are the ducks nesting in a coop or just wherever? Skunks, raccoons, crows and rats come to mind. Perhaps even a dog.

Oh this is what I found (@DemeterAD9

I'm in Ireland , no skunks here and my teenage son is with his mother
Raccoons also no option
Crows maybe , though one nest is well protected from above
No chance of a dog enclosed garden and never had a fox issue (BTW all ducks alive and accounted.

We have 3 cats none of them bothered though one of them is broody (I just am always missing the opportunity to take a picture ... He sits on one of the nest in a break . The other nest is double brooding

Nests re about 2.5m appart and there is a very defensive drake positioned between . I heard no ruckus last night

BTW I cannot upload photos from the mobile app

Hmm the way they are broken doesn’t look like a crow did it but I wouldn’t rule them out if you see them hanging around. I wonder if it wasn’t one of the ducks, they can and will eat their own eggs in order to sort out the good from the bad and get rid of any that were accidentally broken, but to take them that far away from a nest is strange.

Are there any other critters where you live that could have done it? I’m not too familiar with other countries’ pest species.
