I used Whitetail Institute 30-06 Plus protein for my mineral lick and with all the moisture the protein grew mold. I'm gonna dig all that up and replace it with regular 30-06 mineral as it shouldn't mold! I won't be using the 30-06 plus protein again. I know some guys like it but from my expierance it's not for me. I'll let ya know how the regular 30-06 mineral works.
