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
