do you ave hens?
If not, then no they will not fight. They will only fight over breeding rights.
Even with hens I keep 2-3 males in each of my pens with no problems. Thing is you have to have a large pen for this and add them all at the same time. You usually cant have an establish male in a pen with hens and add a new male to it then though, yes then they will fight for sure.
But if added all at the same time, and in younger birds raised together is best, they USUSALLY dont fight. I do have one breeding pen with 4 prs in it, never once picked a feather on any of them.
If you are free ranging them, then you will have no problems either way.
