Sometimes it does sometimes it doesn't. If they are zeroing in one your Cayuga that is because they see him as the weaker. I have never been able to keep drakes together but I have always had females. I have had more than 1 drake but they have to be separated from each other with females of their own. Honestly it's a pain.
I wouldn't try to introduce your new ducklings to this group until late fall because if you don't have enough females it will really get ugly and the females will really suffer. Females can't be with mature drakes until they are of laying age anyway
