Feeding bread to ducks
While we’ve all fed bread to ducks at some point in our lives, these days it is a total faux pas. While bread is loaded with carbohydrates, there isn’t much else for them, so if they eat a lot of bread, it can lead to malnutrition, and a whole host of other problems, including the creation of bacteria that can lead to deformities. If you’re intent on feeding the ducks, opt for cracked corn, oats, birdseed, halved grapes, or duck pellets instead.
