While I greatly respect
@Shadrach ’s experience and knowledge, I think a big part of the issue here is just what has been said. Not everyone wants or needs a cockbird/rooster/etc to be that extremely protective, since most people don’t have the setup for them - they want the quiet fluffy butt because he doesn’t detract from their enjoyment of their birds but is still present to watch over the hens and provide fertilized eggs if wanted. There can be a balance of those things. These people, yes, will want a quieter, less or not at all aggressive male in there because they are always in close quarters with them.
I currently have a young Icelandic cockerel that I hatched and raised. He’s now 6 months old. From the beginning he was very obviously male, puffed his chest and chest bumped my hand in the brooder, herded the other chicks around... we work around each other fine, even though my birds are confined for most of the day. He comes to me when I enter, but maintains a respectable distance; I call him to me when I bring food, then he calls the hens in turn. He once started to dance for me, which ended quickly when I moved quickly towards him and he had to hustle to not get stepped on. Hasn’t tried it since. It also helps I have an older pullet that keeps him well in line, and ensures he’s not being a bully. I’m confident he will be a well adjusted, gentleman of a rooster when grown.
As an example. Cattle have long been bred with an eye to docility in bulls (even so far as to generate an EPD for it) because when you’re working closely with them, especially on foot, those animals are much safer to be around. (and easier on your facilities). Are there places where a much more aggressive/protective bull would be a better choice? Absolutely! Range cattle that are out on acres and acres with a multitude of predators around definitely should have that instinct. A handful of cows in the backyard or even a small operation of 50-100 head where you’re on the ground amongst them all the time, and the furthest they may go is a mile from home? A docile, non human aggressive bull is the more sensible option.
Every situation has its limitations and needs. If the OP is interested in keeping this bird and wants to work through it, taking some of the suggestions to not take eggs when he’s there, etc is reasonable. Taking some precautions to ensure no one is injured is also prudent. If children are involved in the day to day chicken keeping, it may be better for all parties involved to remove the rooster from the situation.
Back to the cattle example. What happens to overly aggressive bulls or bulls that don’t fit within a management system? They go elsewhere, whether it’s to another farm that fits their abilities or on the plate.
Not everyone has the ability, desire, or confidence to work with a more “normal” aggressive rooster.
) some 50 years ago on my Uncles farm, great pride was evident on how aggressive the free range cocks were. I'm British and we call roosters cocks. The aggressive roosters fared a lot better at keeping their hens safe from predators and in a free range environment, and some speed and skill was required when collecting the hens eggs, if one wasn't to end up getting flogged by an irrate cock.
