Actually you
can anesthatize birds, but their respiratory systems are much different that mammals and thus are trickier. If there is an avian vet in your area or one that handles exotics, you could give them a call. It could be expensive, or they might be interested in doing it for the challenge for a reduced cost.
I have often wondered if you could caponize boys and skirt the laws banning roosters. I guess it would depend on how the law is written, but that's another topic all together.
Older farmers do a lot of procedures on farm animals (castrating, dehorning, etc) without anesthesia because they don't have access to anesthesia. Farm animals are specifically excluded from the animal welfare act

Many years ago anesthesia was pretty crude and you were likely to kill animals under anesthesia thus 'brute-acaine'--pin 'um down with brute force and get it done was commonly used. There was even a cowboy boot restraint to castrate barn cats a friend of mine told me about--pretty yucky. Nowadays anesthesia, though not without risk, is very sophisticated and much safer than it used to be.
If you have the monetary resources to caponize, that would be your most logical choice for a back-up if you couldn't find them a 'good' home. Its traditionally done in cocks before they develop their secondary male sex characteristics, so if they have already started to crow, they may continue that behaviour.
