Is it ok to mix the grit and the oyster shell in one bowl?

I wasn't sure what it was when I saw it left in the bottom of the feed pan. So, I went into the fresh bag grabbed a handful sorted it to find what I saw and tasted it.

Then was like, oh it's a rock.
My feed store calls the feed 13-way scratch but I had checked on the mill's website and it is a complete feed that they make for "game poultry". It's 16% protein and is my only local option other than layer or medicated starter.

You live dangerously! Actually, what a cool product! definitely makes things more straight-forward.
