I have a Buff Brahma roo that i have hand raised scence he was a day old chick. I got the breed because it said they were gentle giants, and he is not turning out to be so gentle. He is 7 months old now and is starting to act aggressive. I cant get near him or the hens without him attacking me. I tried walking away slowly from him and he started running after me. If i dont run then when i turn my back he jumps on me with his feet out and starts pecking. I dont know what to do. Is there any way to change his behavior?
