I've settled on feeding my boys S&C frozen and ZP. But I want them to have the benefits of a bone in feeding. Locally, all the wing packs I can find are full of sodium. So I checked out grasslandbeef.com (where I order our own organic meats) to see if I could find wings. I also see that they have chicken necks. That would be about the same thing, right? Or would one be better over the other for some reason I'm not aware of?
