As far as the processing place I used, there is no limit, but you do need an appointment so they can fit you in, especially if you have a larger order. I know the place I used does turkeys, guineas, chickens, and pretty much everything else besides waterfowl.
The place I used is called
Twin Cities Pack Inc. and they are located at
5706 East County Road J in
Clinton, Wi 53525. The phone number is
(608) 676-4428. I know they do turkeys for $8/flat (includes everything) if they are under 25 pounds, and $10/flat if they are over 25 pounds. Poundage is totalled AFTER they are processed, not before like some places do. I asked about turkey prices because I also have a few that I am raising, although they wont be ready until a good couple months from now...
Then there's this place. They are about 20 minutes from the Wis border in Illinois and a small family run operation.
Eickman's Processing Co. Inc., Seward, IL61077
(815)247-8451, (815)247-8463 fax - they are state inspected but I am unsure what they process.

I will post more if I find them. GL in your search. Its hard to find a plant that will process poultry, but turkeys are sometimes considered a 'game bird' so you may luck out there.
