For how long to Mallard ducklings stay with parent?

A duck doesn't actually need its mother. You can buy baby ducks that are 1 day old at markets. A baby duck doesn't get milk from its mother or some type of food from its mother, a baby duck just needs its mom to find food for it and protect it from danger. You can actually raise a baby duck from 1 day old to 2 weeks and even 5 weeks old without its mother.
