I live around a lot of Amish or perhaps Mennonite. They seem to be really keen on helping each other earn a living. So if you can find one that provides a service(fencing,carpentry,etc) you could ask them if they know anyone as that processes birds. In my area there is a amish farmer's market, you know the kind where they sell everything like food, sheds, crafts, furniture. If you could find a place like that, I'm sure you could find someone there. And there are amish in the phonebook that's how I got my goat fence put up. If you look for certain surnames in the phonebook like Esch or Lapp and if they provide a service they might be amish/mennonite or related to someone who is.
