I have a bunch of cockerels that I received from bantam straight run, 3 sebrights and 4 silkies. I'm only keeping one of each with the hens I have, there are 3 sebright hens and 3 silkie hens, and also 1 BA, 1 BR, 1 RIR, and 1 EE hen. Most of the time, i'll let all of then hens out and the two roosters that I am keeping. From what I've seen, the silkie roo I have chosen is more intent on mating with the pullets while the sebright seems more intent on keeping watching and "showing" them food. I've seen the sebright do a rooster dance now and again but he hasn't tried mounting or chasing them. These roos were raised together from day-olds, so is it possible that maybe they are sharing the role of rooster? Or is one just more dominant than the other? Just something I noticed while outside today.
