Appreciate your report and scientific approach, hope your project is going well.
But, why "canned" chicken?
Additives put in compared to fresh chicken could influence the results?
I'm sure your results are valid, no question about that, but a more interesting question would compare fresh chicken backs (which are commonly available, and inexpensive, at most meat markets and grocery stores, and are more commonly used) versus salmon pieces.
Again, congratulations on completing your project, and not meaning to be critical of your testing.
