A female can definitely be the boss! My little Punkin, a Serama, and by far the smallest, has always been the boss. She had it out with a cockerel, and she won. He never challenged her again. She's tough!
I'm going to take some wild guesses here, and I mean WILD! Young Polish are so hard to sex, but for fun, I'm guessing the pullets to be #1, 4, 5 7, 8 and the rest cockerels. How old are they?
