I have 3 red pyle OE roos and the oldest is wonderful to his hens but I dont know how smart he is? They 2 younger ones( this summers hatch) are awful and I have had to seperate them from the flock. (same problem as yours) And now I am facing your dilemma, just cant bring myself to that point yet. I keep thinking that they might settle down as they get older.
Any way I like my older roo but dont know how well he would protect his flock in a free range situation
