Quote: As you're pretty new to this by the sounds of it, if I were you I would spend a good amount of time out in the yard watching, observing. Some warning signs are obvious in retrospect but not at the time. Experience helps a lot.
Any animal can be dangerous in some way or another, no matter the size or age or gender or breed or whatever. No chicken, dog, cat, horse, cow or whatever is automatically dangerous to us (or other animals) simply by virtue of being male and undesexed. His personality and ancestry counts for a lot more than his gender, as a rule.
There's a great myth of the inherently violent male that's perpetuated by those who keep and breed violent specimens. It's like those folks who gasp about stallions being used as normal horses, ridden and worked, etc --- while some other folks just get about the job of training it like any other animal of its type. It's OUR mentality that counts far more than the gender, breed, reproductive history, or any other trait of an animal.
The most recent breeder of the ancestors of your males is the biggest determinant of whether or not you have female-abusing, human-attacking or baby-killing males. If they thought it was all 'just the way it is in nature' and 'normal for a male' --- then they bred it on. If you cull for bad traits you get great males who will never harm females, babies, or humans. Or even each other. It's all strongly heritable.
If he ever shows signs he thinks you are also chooks or he is also human --- cull. It's totally normal for a chook to try to mate with or attack a human if it does not understand the difference between you and itself. In my opinion artificial insemination and gender separation practiced in hatchery bred birds for many generations is responsible for much of the dangerous and defective attitudes and instincts these birds have. I think for human safety as well as general flock health it is best that hens raise the young, not separate from roosters, so the animal's ancestral memories and instinct of its family unit are triggered and reinforced.
Some warning signs to watch out for:
- He gets overexcited when you pick up another chicken, maybe attacking it or you in the process
- He pecks your hands/arms/feet/legs, especially on the back of the hand or the top of the foot, and maybe tries to climb on. He may not do more than peck at you, but it's a vague idea to mate with you causing it
- He does the 'happy feet/scary feet' dance towards you; the one with one wing dropped, sideways approach
- He ducks his head into his shoulders or lowers it, facing you, 'squaring off' or 'sizing up' --- fighting stance
- He tries to get the other chickens to view you as a predator, always giving the panic/alarm call when you approach, or the 'alert' noise when he sees you. It only takes one chicken to teach a whole flock to freak out
- He never ever accepts handling, and maybe perceives you as another rooster when you do handle him
- He puts up hackles at you or pecks at things he's not eating while facing you and watching you
A calm and trusting rooster (the safest sort) should be relaxed in your presence at all times. It's a surprise for many, but you can genuinely see intent to harm, a 'nasty eye', in a nasty rooster. Some of the signs I mentioned are not serious attack warnings and may never lead to an attack but are all defective mentality symptoms and I cull for them since I've watched what they lead to. (Nothing good).
If careful handling and a calm, unthreatening social presence are maintained by you, they should view you as the provider of all good things, and be quite attracted to your presence in a peaceful and nonviolent manner. It only takes one or two slip ups to convince a spacky young chook that you're hunting it, so it helps to be mindful of their body language when you're out and about --- they may think you're chasing them when you're not, for example. I don't use an automatic feeder so they are taught to come to my call and view me as provider.
I don't treat my roosters any different to my hens. I don't personally believe you need to. No violence is required. Fear is not something I want my chickens to feel when they view humans, I want them tame, friendly and calm, because I have various small children from my family and other's that roam the yard with many roosters and cockerels unsupervised at any given time, so I need the chooks to be as trustworthy as possible. Friendliness is more trustworthy than fear in my experience. Chickens often get game enough to front up to a bully, but rarely decide to have a go at another creature they view with positive memories.
Their prevailing attitude towards humans tends to breed true in most cases, too. I run a ratio of males to females that reaches 50:50 and up to over a hundred birds quite often, so for all reasons the temperament of my birds is paramount --- for flock and human safety. Never breed a male who attacks humans.
I handle them all at hatching, usually, and a few times each while growing up, and my rule is that they do not escape my grasp by struggling. They will be gently and calmly released when I say so, not when they decide. I sit with them on my lap and if they freak out when my hand is not restraining them, jump up and run away, we will repeat the exercise. Only calm retreats allowed.

Any bird that refuses to be calm as an adult, after I've put in the time, is incorrigible and will be culled or rehomed. I can't have feral-minded birds.
Anyway, it really is each to their own, others have their own standards and methods and beliefs. But I hope you find what works for you. Best wishes.
