Believe it or not, I have found the bigger the rooster, the less aggressive he is. I have bantams that are vicious and seem to suffer from the napoleon syndrome.
I have a few Rhode Island reds that look at me as walk through he flock like "Geeze, do I have to move again?" and I even have one that will eat out of the kids hands.
Years ago I had a jersey giant rooster who was so relaxed, people used to pick him up and carry him around.
That being said, remember, there is always an exception to every rule! If that 10 pound giant had decided he was going to be mean, he would have done some serious damage to anyone he decided he did not like.
I do not know the opinion of people here on the forum and if I offend anyone I apologize in advance, but I do not like to take chances with people getting hurt when they are visiting the barnyard. I clip the spurs of my roosters, with-in reason. I know some people have talked about covering the spurs.
