I hand raised my little flock from hatchling age. I purchased one rooster and was given a surprise rooster chick with my order. I now have two roosters and 11 hens. My roosters did not like being handled from day one. I continued to try to gently condition them, but they remained aloof. They are now 6 months old. My Black Australorp has become very aggressive and has attacked me twice from the back and the side in the past few days. I don't understand this and I am not going to tolerate it. I was very aggressive right back at him today and he backed off and gave me my space. I was not approaching him either time. Should I even hope he will stop this behavior? Thank you in advance!
