Hi all, I have 3 B.O. hens, 2 bantam hens and 1 bantam roo, they are all 14 weeks old and were raised together and have been peaceful. I added an 8 week old Australorp Roo, who is now12 weeks old to the flock. Everything had been fine, my little black Jap bantam has been the head Roo and still is. Well, for the past week the Australorp has been really mean with the hens, mostly when I come out to feed. If I pick up or show any attention to one of the hens he waits til I walk out of the coop and he will run over to her and peck her on the head or neck really hard and then he will chase after her and grab feathers and hold on while the poor hen screams and drags herself trying to get away. He also does this if one gets too close to him. No problems with the bantam Roo, they avoid confrontation with each other and seem to get along fine. He just seems to be really mean to the ladies. My bantam Roo is so sweet and calls the girls over for treats he finds and just so exceptionally sweet to all of them, but they all run from the big guy and crowd away on the other side of the run from him, if he comes over they run to the other side. I do plan to build another coop and split the bantams up from the large ones after this heat breaks. I also have 7, 5 week old LF girls that I will be adding with the 3 B.O. girls and this Roo, that is, if he straightens up. I just can't understand...I thought Autralorps were suppose to be sweet natured birds. This afternoon he seemed really agitated and just went after a few of the hens including a bantam hen, after I walked away I watched from the window he just kept on pacing the run like he wanted out and then would go after them again chasing them around and around and pecking and grabbing their feathers and pacing until it was dark. My question is, is this normal acceptable behavior for a Rooster???? Should he go or should I give him some more time to see if he adjusts? I'm about tempted to throw him out of the coop tomorrow on his own to let everyone have some peace. I just don't know what to do. What would you all do?
