The Bredas are such docile birds they will often just hide their heads in a confrontation. I'm glad the orp backed off. My orps aren't normally aggressive either. I have a barred rock that is a total jerk. I had to throw him out of the rooster pen because he would pick a fight with the other roosters and not give up. He is a docile bird other wise and is scared of his own shadow. He decided to take up residence with the layers and sleeps in the far coop and the other two roos sleep in the nearer coop. I'm glad they came to a truce.
