I think temperament can be inherited to some degree. I raise all my birds the same, and I remember one batch from eggs I ordered that turned out just the absolute rankest males I've ever encountered. I won't go near that line again. I won't breed a really rank cock if I can avoid it, either.
OP, in your situation and with your goals, I would choose your hens and then try to make sure you can separate who laid what. Then, when you see your chicks grown, if any of them have what you're after you know who to breed again.
