For those of you in the know...

Hello my fellow chicken chums, I have a question that some of you in the know might be able to help me with. My aunt is now in possession of 20 week-old chicks and she wants to have the males caponized. I know this is an easy procedure to have done at a big hatchery facility, but is there any place I can take the birds to have them altered other than the local dog and cat vet? Where do backyard farmers take their birds to get fixed? Thanks for the help folks, see you on the flop side.
