How often will males fight?

[C&Rman]

I am going to be hatching my own peacocks, and I already have 2, but I probally will get a male. I am going to be placing them in a 20x30 pen.
Will the males tear eachother apart?
Also will the peahens fight too?

So long as there are enough hens and they have enough room,you do, they should not fight that often and violently, at least that is what I have heard
