Thank-you so much for posting this question! Bought a bag of Purina medicated chick crumbles last week and had a explosion of moving dust. They were on everything in a 6' radius of the bag. Gross, gross, gross. Had no idea what they were. All the chicken feed, dog food, and bird seed got double bagged and sealed in plastic buckets and cans. Glad to hear the feed is still usable, hoping the bugs do not find their way to the pantry.... Shudder.
