Just the toms, no hens? If so, let `em at it (if they have sufficient room to get away from each other when one of the two concedes). Fall coming on is pretty much Spring in Reverse (turkey hormones rising - but not as much as during mating season) so sparring will be the order of the day. The loser will mope off, snood dragging the ground, beak bit and abraded, but he is only mulling about how to best the Alpha in late Feb.-Apr.
If run is small and there are hens I'd keep an eye on them. The hens can sometimes gang up on the losing tom and do some damage.
All of ours (toms and hens and soon to be jakes and jennies) were wound up the day before yesterday when the sun came out and the temp. went up (flock of 28 Wild Easterns hanging around - in woods but visible from runs - didn't help). Today they are all `friends'.
We've alway abraded tips of spurs from our toms so accidental, serious, lacerations are unlikely. We've also resorted to pine tar (slathered on heads/caruncles - not above eyes) that slows them down and disinfects wounds. Sometimes, just leaving one tom outside the fence and one inside will allow them to chortle and nip - but prevents neck wrapping knock-down-drag-outs. 48-72 hrs of this sort of separation - in the Fall - will usually leave them tolerating one another's presence.
