My rooster and drake use to get into fights and most of the time they worked it out themselves with me staying out of it. If your drake is out to injure your Roo, I would keep them separated. If your drake is mating or trying to mate your hens then he definitely needs to be kept separated from the [chickens] seriously a drake will kill a hen if he actually mates with her it's just a matter of time.
Yes, I understand, I time before i would even make a meal of them.
But It's not that simple, that pair is together from birth, and they are not my birds, yes they are, neighbors gave them to me, cuz the cull all their flock, but wanted to ducks be with me, cuz they childs could go and see them and give food, cuz those birds was a present for childs. Btw, those childs dont care about them. So thats not a point.
First when we bring them with my flock, 50 chickens, one main rooster, one cockerel that time. They go fast thru all teritory showing they're gonna be the bosses, while duck grab a hen, then rooster run there screaming and attacking once, but ducks are so dominant and just go forward till chickens just run away.
Mainly all is okey, ducks often just push hens with beak makin them go away, so as chicken do to chicken. But mostly I didnt like how drake is minded versus my rooster, mby he just knew hes dominant, but drake want to take over. I have growing 3 more roosters, including my 9 months old Vorwerk, who isnt runing away from them like from fire, but do 'faceoff' if they come to him, till one just turn away. Mby together they gonna kick his ***, so I am interested how this all can play out with time.
I had hold my old Rooster in hands, and drake doesnt like that. If I put rooster down and hold, drake is coming to us, and even scare a **** out of me.

Like ready for war.
That drake is strong. Duck kin is strong I guess.
Mby holding rooster i need to slap that drake.
