I have a 13 week old Buff Orpington roo who is as big as my year and 3 month old hens. My roo has 7 of "his" hens that he was grown up with. They are all his same age, and he treats them as a roo should. My two flocks ( the 5 older hens and the roo with his 7 younger hens) are separated in a see-but-cant-touch pen. And they have been for about 2 weeks or so now. I thought I would let one of the calmer older girls out this evening to greet the new flock, but my buff orpington roo ran up to attack her. He jumped and pecked and pecked and jumped on her- aggresively not in mating. I had to remove her. Is this normal? I am brand new to intergrating and have done some research. Did I wait until he was too old, too big to integrate? He also was a surprise- I didn't plan on having a roo. I hate seeing them attack and fight; I have read that that is to be expected for the first couple days. Any help is so much appreciated. My biggest worry is the getting the roo to accept all of my 5 older hens, and the 5 older hens to accept the bantams I have. Thank you so much in advance!
