Fiesty game hen

[Chickipoo]

I recently purchased several hens, one Poland, two comet/polish mixes and one game hen. The game hen is continuously attacking the other three. Will this ever end? Or am I going to have to sell the game hen? I will also be placing all hens in a coop with one barred rock and one leg horn rooster. Will the hen attack them too? Thanks for all your help! I'm new to this!
