My flock is now 9 weeks old. I have an EE that had started to show a mean side. He's the only one crowing at this point and is definitely bigger than any of my other chickens. I believe I could have a total of 3-4 roosters in a batch of 11 including him. At what point is the bigger one just establishing the pecking order or is just mean? He actually held down the head of 2 chickens tonight and it was 2 I'm wondering if are males. Please some insight! Give it to me straight; I dont want a nasty rooster around. Thank you!
