Call duck drakes fighting

[easterlyfarms]

I hatched these guys together last june. there are currently 5 drakes and 4 hens, a few began fighting each other about a week ago. currently the aggressors are separated. my last choice is getting rid of them. should a reintroduce them, and let them fight it out or what? any input would be great.

There isn't enough hens for the Drakes. They are fighting over breeding rights.
