In my opinion....there are too many nice roosters out there to put up with a bad one. Three weeks ago I was dealing with a roo problem that has cleared up now (apparently), but I will have no hesitation to give him away to our local church (they feed the immigrant workers) for someone to have dinner.
Like you, I can't kill/process/eat my birds....but I can give them an opportunity to live a good life, but if that doesn't work out, I make myself feel better by knowing the bird is going to feed hungry people.
Good luck - I hope all works out well for you!
