Yes, it will have been a fox.
http://www.discoverwildlife.com/british-wildlife/how-identify-egg-thieves ... ducks leave the nest to feed and bathe/preen, covering the eggs with down but if the duck is on the nest the fox will take her and then come back for the eggs.
If someone had stolen the eggs the duck would probably still be around, and is likely to lay a second clutch.
