It could most definitely work. However, I wouldn’t start out feeding all those protein sources at once. Pick one (chicken is usually good) and make sure they do well, then add in another. Go slow. I started out feeding a single protein source for about 2 weeks, then added another, etc, as well as organs. (Keep in mind things like hearts and gizzards are considered muscle meats, not organs; though gizzards are great for teeth on smaller animals that can’t swallow them whole.)
I personally don’t feed pork or fish for various reasons. It all boils down to what you can ethically source, what your animals do well on, and what is affordable. Turkeys are really cheap after the holidays; if you’re in the states, you can get turkeys (even organically raised) for cheap after Thanksgiving. (Our stores have whole duck, too, during the holidays.)
If at all possible, it might help to locate a pro-raw vet (they’re out there, trust me!) who can help if you run into any issues. Our primary vet is 2 hours away, simply because the clinic is very holistic. And as bad as the term “holistic” is thrown around anymore, they truly embody the term in their practice. Best of luck.
