Feeding the ducks with leftover bread is a favourite pastime for many but experts have warned too much white bread can be bad for them. It seems it can leave ducks bloated, ill and in danger from predators as it is less nutritious than their normal food. Experts have warned that ducks may even develop a craving for treats such as bread, leftover chips and takeaways and become reluctant to forage for food. People have been urged to swap white bread for more nutritious food such as grains and pieces of cut up vegetables. So next time you feed the ducks perhaps you might need to take them some more healthy snacks.
