Subject: Can mallard ducks move their eggs from the nest.

While on vacation a female mallard laid 12 eggs in the center of a large 
plant near a house and covered them with feathers. 20 days after returning 
from vacation and watching the female duck on and off sit on these eggs, 
the eggs have disappeared from the nest. No sign of eggshells and the nest 
in still in good shape. Closest water is at least two blocks away.
Can ducks move their eggs or is it more likely something got them?
