Yes, a duck can lay eggs more than one a year. I have ducks and chickens that lay eggs daily. (I know that some birds, if their eggs are damaged or ruined in the early stages of nesting, will lay more eggs, most often in a different nest location. Robins and pigeons do it all the time...well, each spring, anyhow). most birds can do it from 1-4 times per year. In the wild, birds lay eggs twice a yr.(House Wrens will build as many nests as they can before the season changes.)
