I think you'll be okay if you're just adding a little chicken. You have to start worrying about supplements when 1/3 or more of their diet is coming from human food. I boil a chicken breast every few days & cut it up to use as treats. If I have some leftover in the fridge that's going to spoil soon, I shred it up & add it to their food.
