Fighting males?

[Dragonflywest]

I'm not sure what info is relevant, so I apologize if it's long. I have two male 1 year old ducks, one jumbo pekin and one Indian runner (figured out bedsbreeds looking online). I got them from the same store at a random pick. Starting about a month ago, they started being very aggressive towards each other. Never had a problem before. The jumbo grabs at the others neck, usually initiating it. They pull at each others feathers, knock each other down, etc. I thought, something about mating age? A week ago I adopted two more ducks, one male jumbo pekin and one female Indian runner. Is the imbalance of sex bad? Too many males? Or is this normal? The first two males don't really bother the new ducks, they just fight each other. I worry the jumbo is going to really hurt the little runner.

And you have every right in thinking that, the Runner is no match for the Pekin, I'd separate the 2 Runners together and look for at least 1 more duck so the Runner drake doesn't breed her to death [much better having at least 2-4 ducks per drake to keep the girls from being over bred and injured] and
