Drakes on their own

Hi all,
Can any of you duck lovers tell me if drakes were kept, say 3 or 4, without any ducks around, would they get on, and would they be better from the same hatch?

Thanks in advance folks

I used to have 2 little cockerels that lived totally free range with the ducks down at our lake and they used to hump the ducks.   
 My terrier given the chance humps the ducks and the cats, and my tortoises hump each other. Doesn't matter if its boy girl, girl girl or boy boy. 
I wouldn't worry too much about it
