You may be right. Our experience was mixed. We had an amerucana rooster that was raised with a round of pullets. The next year we ended up with that barred rock rooster (the one I described above). Most of the original pullets wanted to stay with the amerucana rooster, but a couple started "being" with the younger one. It was like a daily soap opera for a while. I could hardly keep up.
It has been two years, and basically the Barred rock just mates anyone when he can when the amerucana is not around, but some of the original hens still never let him mate with them. I wonder what would have happened if he was the only rooster, but I think this is what Canned Monster is talking about.
