ducks can also have treats like other pets but you must treat the responsibly and not give them treats all the time. good treats for your ducks are things like plain scrabbled egg, sliced tomatoes and diced veggies, finely chopped lettuce, hard boiled eggs, earthworms, meal worms, blood worms,slugs and bugs. there is also things you shouldn't give your duck/s as a treat -: junk food, cookies, bread, bread products,ice-cream, nuts, seeds and alcohol (should i even need to mention that) if you feed your duck/s any of these thing sit will shorten their life it will not just kill them. remember to treat wisely!!!!!!!!!!
