I remember my grandma going into her coop with a axe handle to fight off the agressive roosters so she could get the eggs. She use to tell us kids dont go in there without me or your G-Pa because those roosters wilk hurt you. We use to watch her smack them upside there heads to get them back and we use to ask what if you kill one when you hit it, all she would say was "We will have dinner then wont we"
My grandmother used to do the same. I can now have the exact same flock but have roosters that do not pose such problems. Somewhere I learned how to behave around them that prevents the aggression from getting underway. I still use an ax to kill but rooster is selected of the roost at night and selected for attritbutes not directly related to aggression rather than as a product of self-defense.
