Sounds like my cousins's rooster she has. He is so mean that he was attacking them when they would leave their house. Her husband, who is a police officer (in Knoxville) actually shot the F*&%er in the chest and its still walking around crowing to this day! They now refer to him as the Undead Rooster!
My great uncle had a rooster, Percy, that would do the same damn thing. He would chase you down and you better hope he didn't get close enough to spur. He was one mean spirited rooster, that is for sure.
