Brian - where are you located? (You say PA and NJ - I am in NJ, near the PA border).
I wouldn't suggest turkey necks - a lot of animals vomit bone on them, and they are not enough meat for long term feeding.
I recommend starting all new animals out on chicken leg quarters- right amount of meat and bone in my opinion, and very easy to get for most people (and very cost effective!).
I wouldn't worry about using a new novel protein at this point - your dog could very well be allergic to a grain. I would just give the raw diet a chance - novel proteins will cost you a lot more to feed 100% of the time, rather than just as a supplement.
Depending on where you are, I can give you some good pointers on where to get food, and even the info for my co=op I am a member of.
Just a side note - your vet may not be pleased not because he is losing business (because you aren't buying z/d anymore) as someone else suggested but because they honestly believe that the diet is dangerous or potentially will not help your dog. While I am a raw feeding vet, many vets are not educated on the diet and cannot help but do the knee-jerk reaction (heck, I did it too a decade ago!)
