I get that, that's a larger step in chicken care. I was there myself.I'm not quite ready to kill chickens yet. I know it's a reality I'll have to face one day but they are mostly pets right now. You're right about finding another rooster, there's always free ones on Craigslist. I guess it just never occurred to me to get another one.
You could just post him for free and just give people the heads up he's aggressive. Someone will most likely pick him up to eat him anyway.
