A duck will eat everything and anything -- including things which aren't even food, sometimes. Pizzas have a high oil content, which is good for ducks, but they have high sodium content, which is bad. Letting your duck nibble on a small piece of Pizza once a month won't hurt it, but feeding it all your table scraps frequently is risky. They are like dogs - they will eat until they can hardly walk. It's better to limit their exposure to human food to things like leftover salads, fruit peels, eggs, etc. Ducks are insect vacuums - foraging outside is good for them. Be sure to supply your duck with an enormous amount of water to drink.
