The thing about "taming" an aggressive rooster is, even if one person gets that rooster to stop attacking them, the rooster can - and often will - attack other people anyway. Just because it doesn't attack YOU, it doesn't mean his aggression is gone. Also, what kind of life is it for the rooster to have to get knocked around every day when a person goes out to pick eggs and has to defend themselves from that rooster? I have chickens for enjoyment and entertainment (and eggs and meat). When a chicken is not giving me joy, it has to go away. I'm not going to keep a bird that I have to continually duck and dodge and avoid so I don't get spurred or flogged.
