Quote: Once he grows spurs, it becomes a big and potentially fatal deal. Spurs can do a horrific amount of damage.
Quote: Yes. It is your prerogative and responsibility to handle them, for their own good. This includes handling them at will which will help them learn to trust you and submit to whatever treatment you need to administer. This is necessary for your safety and well-being as well as theirs.
He should trust you too, especially if he has never seen you abuse them. I have had chickens of both genders who showed this trait, of attacking when I picked up another chicken, and after it became obvious that they were going to harm a human or the chicken being held, I began to cull for that behavior. They left me no option. Because it is a mental aberration, they lack the self-preservation instinct that should kick in if you slap them away or something like that; instead, they become riled up and even more aggressive. Any chook with a normal mind would realize quickly that you are capable of killing them with one blow. But this is not a normal mindset. And it isn't helped by people breeding human-aggressive birds who they gently slap away as the animal gets more and more worked up.
Quote: In chicken language, you yelling 'hey' would have most likely been perceived as you panicking or crying out in pain. They do not express hostility or disapproval toward one another with a yell. But I understand your reasons. I don't believe punishing chickens is helpful. Some people 'cure' their roosters of being violent by harassing or harming them, which is never a permanent cure from what I've seen and heard. Or tried --- I have tried everything everyone else has stated that I've read on these forums. It became ridiculous for me to spend so much time of day 'maintaining' their retraining (read: reminding them) something they will never learn. I started with gentle non violent methods, worked up over time as everything failed to the more violent methods, and then decided not to do it this way; that's not the flock I want to share my yard with, those are not the roosters (and hens) I want to breed on with. It's insane.
I cured my flock of violence by culling the violent ones. They are the extreme minority but it breeds mostly true. Happily, peaceful attitudes breed true, mostly, too.
In my experience they do not start to show aggression and then stop; it is a reliable sign of a strong mental bent. In future he will most likely attack again (it always went this way with my 'duds') and it will likely get more and more serious. One issue is that they naturally go for the face, and many are sneaky enough to wait until you're bending down and only attack then, after days or weeks or months of pretending to be uninterested. But others are quite capable of jumping up to your face while you're standing; they don't even need to fly to do that. As a general rule, they will charge when your back is turned, without warning, if they are so inclined. I would always be on my guard around him. They're very fast and can blind, mutilate, or even kill you.
Quote: Personally I would cull him, but I understand if you choose to try to retrain or rehabilitate him. I would be prepared though for this behavior to worsen, and expect him to use his spurs on you or someone else sometime in future. Some people say they've 'cured' their violent roosters but I have yet to see the cure that has stuck in the long term. Often a month is the top end of how far the cure stretches. His entire mentality is incorrect for him to ever attack you in the first place. It's a symptom of deeper issues.
If I had to hazard a guess at what was going on in his mind, I'd bet he perceives you as another rooster, trying to mate with a hen, and he perceives himself as dominant over you or able to dominate you, so promptly put that notion into action. From your reaction, particularly if you released the hen, he won, and the idea is reinforced in his mind. Obviously a creature that size displaying the default mentality of being dominant over a creature your size shows it is devoid of comprehension of the reality of the situation. In other words, mentally unwell.
Quote: Way too many for one roo. I would get another, hopefully an older adult, to hand his fluffy butt to him and distract him until such a time as I am ready to cull the younger roo.
Sorry to sound so negative. I tried with my bad roos at first, but gave up when nothing I did ever worked. I have small children running about the yard at will, as they must be able to do, and cannot tolerate the risk of having a rooster who will attack without warning, or breed human-aggressive offspring. I have tested whether or not it breeds true and know it does. Not 100% of the offspring will be like him, but too many to be worth it, and it can continue to surface for many generations. The risk to human life is too great, in my opinion.
One random possibility is that he is sexually attracted to humans. That often starts to show with bizarrely strong fascination with humans, followed by attempts to mount a hand or arm, or foot or leg. It also often descends into violence, and also often breeds true. These are deeper, powerful patterns of behavior. Natural instinct driven behavior has been replaced with something thwarted or misdirected. We are not often able to manage instinctual drives, rather we tend to breed them out of, or into, our livestock. That's done by culling those that don't fit the most profitable or beneficial social requirements we have.
Best wishes with whatever your choice is.
