I find that incredibly sad both for you and the rooster.Why would I want to keep a dangerous animal that I had to avoid?
I have no issue coping with and avoiding the black widows and the copperheads in my environment, but I shouldn't have to avoid MY OWN LIVESTOCK.
I am willing to eat my way through as many roosters as necessary until I get one who doesn't see me or my family as a threat to his flock and isn't stupid enough to attack the giant who brings food and water.
You don't have to kill them. You just need to learn how to cope with them.
I found that eventually those roosters who tended to be defensive and prone to protecting their hens, their hens eggs and any resulting offspring grew up to be wonderful creatures deserving of the respect they demanded.
