You didn't mention the Polish being aggressive in your original post. Ok, from what information you've provided, you are dealing with 2 roosters, entering adulthood, and hormonal. They've been establishing pecking order, the Polish is Alpha. He's also trying to get you to recognize him as Alpha, instead of the other way around. That's where I would start. Get the Polish under control. You might want to try the method Beekissed has recommended.
When you establish yourself as Alpha, and get the situation under better control, it will not hurt to rotate the roosters with the hens. I do it all the time, because of my breeding program, and they do fine with it.
