That fighting is as normal as strutting. I would let them work it out and soon their pecking order will be established. My two BBW hens kicked the snot out of the two toms I wintered over all winter long, and when they had established their dominance there they went after each other. Gracie is the instigator, but Eva usually ends up on top. This years first batch of BBW jakes are between 25 and 30 lbs. right now and Gracie has taken to threatening them any time I'm out there or near one of them. They are very possesive and protective of me and my son. My husband they could do without.
We even have the little Midget Whites attempting to take on the largest of the BBWs. It used to be really funning watching the tiny ones run around between the big ones feet and then fly at them to attack. I have most of my ages out together, but the youngest that are only 5 weeks, also MWs, are in a pen out near the others and they fly at the bigger turkeys trying to pick a fight, and off course smack into the fence they go. I don't worry too much about them as they can pretty much take care of themselves, but I did have a MW with a pretty large torn spot on his neck that I had to repair. Little bugger got down from surgery and went and attacked the biggest tom.
This fighting is why the large commercial places will debeak and clip their snoods.
My Midget Whites also chase off the ducks and geese that used to come and pinch the BBWs. Yeah, for those fiesty little Midgets! If something starts running they run right after it. The chickens have stopped coming up the hill to steal the turkey food.
