I have raise a decent amount of ducks----but they are always on the lake/pond. They get probably everything they need from there---so I have fed grain/scratch mainly just to keep them coming to the feeding area. But if a person does not have a "working" pond, just penned up Ducks with a water pool----for sure they needs more than scratch.Yes....I agree it's not a balanced diet....The guy I get all my Ducks from never feeds any of his birds a balanced diet...They come here and thrive...He only feeds cheap strait grains...Although he does have 300 Birds....![]()
