I just bought 100 pounds of cracked corn that was manufactured and bagged in August 2016 and it is INFESTED with weevils. It is 9/7/2016 so I do not think old feed based upon stamped manufactured date of August 2016. Previous 2011 post stated to take feed back if infested with weevils. However, would this not be additional protein source for Muscovy ducks. They love worms and other insects. Any thoughts?
