I am definitely following this. I've got a 4 week old bully cockerel. I've wondered if he has a mental issue. He is nasty to the 5 girls with him, which is different than attacking people. I can just see this bully doing this with time. When I pick him up, he screams but it's not like a scared scream, he is angry (not that I speak chicken or anything. I've heard his scared scream and that's not it. He sounds really angry). He's really stressing the others so I put him and one of my 8 week old Cockerels (that is sweetheart but going to a new home with his flock ates, 2 other cockerels, this weekend) and this little 4 week old bully wouldn't back down and started going at the face of a cockerel twice his size, not once or twice, but many times. The Barred Rock 8 weeker, would peck his tail feathers and the 4 weeker did his growling like sound and then started screaming. He did go right back for more every single time though. I don't plan on keeping a cockerel/rooster, but I am trying to give him time to get his mind right before I decide what to do. I've said this before but it's like the girls are walking around on eggshells all the time and the stress it's putting on them is uncalled for. Best of luck to you. I'm grateful for your post as it's helping me learn how to deal with this
