With WildThings Swan and Duck, we can prevent un-eaten food that sinks to the bottom of the lake and rots and eventually causes pollution. Prepared as a small, dry-pellet that floats on water and remains accessible on the surface longer. Carbohydrate-rich foods, such as bread, can seriously harm the health of wildfowl, increasing the risk of deformity, disease and malnutrition but with WildThings, much-needed nutrition is provided while helping the environment.
