There will have to be time where they all get acquainted. once ducklings are large enough to be out side them fencing with your duck on one side ducklings on the other for a while till they can get use to each other, you can't just put ducklings in with an adult that doesn't usually work out very well.Im sorry, I meant to say baby ducks...I have chickens and it just came out that way..so she would accept baby ducks?
