I totally agree. The best you can hope for from your rooster is a warning call to the hens. I have free range Old English Bantams that live in a fenced pasture. My rooster is a rotten little thing. He will not tolerate anyone or anything getting close to the hens (including us). He spends a lot of time under a bucket when I need to worm, clip, trim, etc. hens. Nobody can understand why I keep him. Answer is: He has demonstrated twice that he would give his life for the hens. Once with a Siberian Husky and once with a rogue, much larger rooster. Patched him up and he's still kicking. He doesn't even eat when they are out in the pasture, just watches out for the girls. He has no idea that he is a little guy.
I guess that is the benefit of having a tiny rooster with a big old 'tude when it comes to humans. Just put a bucket over him. I don't think a bucket could contain my LF Cochins or Cornish if they got it into their heads to attack people. I have a kid (and another on a way) and a sassy banty could still hurt a kid, but if you can manage him and he is that good....
