Can I feed Ducks Bread? While Swans and Ducks seemingly enjoy bread and other savoury items, experts warn against these foods which are all high in carbohydrates, sugars and salts. This is because these items can lead to serious health issues in Swans and Ducks, such as becoming overweight yet paradoxically malnourished. This is due to the bread making the animal feel full even when they haven't had all the nutrients, vitamins and minerals needed to stay healthy. It is much better to give them nutritional food!
