you do know caponisingt is extremely invasive, requires you to burst an air sack and comes extremely close to their aorta while decrowing surgery is not far off from a tracheostomy which is sometimes done to people even without anesthesia. I think what freaks you out is that caponising has been normalized to you while decrowing is new and scary. A lot of good roosters go to their death due to pesky neighbors and I say if a small surgery gives them a shot at a happy life with hens and a person that cares about them then go for it.Don't know what you mean by 'decrow'. Some people caponise but that is normally done at a younger age. It doesn't necessarily stop crowing but will make them infertile. Any surgery to remove the crow will put the cockeral at risk and is just wrong. You can use a no crow collar but the effectiveness of these are varied. IMO if you have a cockeral let him be a cockeral. If your not allowed one or don't want the crowing, rehome him.
