Alison- I have someone who will teach our meetup group members how to butcher, but he is very busy right now so even if you wanted to travel up here to learn, I cant say if he is available. I could ask him....and I know that he is planning on doing some butchering soon. Some farms up here also teach weekend classes.
When I grew up in Brooklyn there were live bird markets and I think that they still have them somewhere out there. you may be able to get them to show you or to do it for you. If you do it alone be sure to study it on youtube or something like that. Its a pretty big job and you need to know what youre getting into.
UConn's animal extension thinks that the most humane way to put a bird down is with an electric shock in the butt. Ive also heard that the most humane way is to dislocate at the 5th vertebrate, just firmly pulling. I have done that before but its hard to figure out if you've done it enough or properly.
Many south American immigrants know how to do this and the cleaning, and its worth it to ask around. I know guys up here from south American and also Eastern Europe who grew up on farms and know all of this.
Finally, there was a butcher in westchester that did the cleaning and cutting if you did the killing, but Im not sure where they are.
If you look around and still have trouble, email me privately and I can try to put you in touch with someone to do this for you. The question is, how far can you transport them and/or do you need someone local to do it? Melina
