Hi, we raise Silkies and our first rooster was a barn burner. You had to keep an eye on him every minute cause he would jump you the second your back was turned. "Can't abide by a rangy Rooster" but eventually struck a stale mate with that bird, his name was Soldier. Must say though he was beautiful and protected the flock very well. One day we hatched out a bunch of Silkie eggs and wound up with about 5 roosters and once they came of size one of them tore old Soldier up. We have since decided that one rooster is enough and the one we have now is a sweet heart.
Bantams roos have a rep for being pretty fiesty and I know the couple of Cochine roosters we had were also tough. But its not just Banties that can be problematic, when I was young my grandma had a Leghorn that terrorised me. I can remember being chased by that bird every time I came out of the house. In those days the chickens just roamed freely around the place and would hold up in the barn (or trees) at night. Grandma always knew where to find the eggs but for me every day was an Easter Egg hunt.
