I would wonder how spoiled or moldy this stuff is, and I'd throw it out.

What you have in reality when you feed weevil infested scratch feed is cracked corn. Liking mold or some other micro organism growing in your feed (like happens when you fermint your chickens' food) is not a concern with weevil infestication but the fact that the weevils have ate away the best parts of the grain kernel leaving only the hull. So grain infested with weevils is none or little worse than feeding cracked corn.
