Agreed.People will disagree, but while chickens should be calm around you, they don't really develop a trusting relationship with you. They have a very small brain. If I wanted to keep that cockerel, I would walk up to him, untill he moves. I would insist that HE kept a distance of 4-5 feet away from me. I would not make a pet of him. I don't want them terrified of me, but I do want them respectful of me and other humans. A violent, aggressive rooster is a very scary animal. They can do serious damage, and have ruined the whole experience for a lot of people.
If this is your first year with chickens, I would cull all of them, and get some experience.
