You could actually add any drake with preferably the same size as the ducks to the flock. A larger drake might be too haevy for the ducks and injure them while a smaller drake has problems to mount his females.
They are all mallards (except for the muscovy of course) and will recognize each other as flockmates.
In my opinion a flock should always have ducks and drakes because it is more natural for the birds to have a partner of the opposite sex.
