I just opened a new bag of scratch and fed it twice before I realized it looked funny. It looks all powdery and broken down. Even the corn in it is crumbly. I first suspected bugs in it but I can't find any bugs in it. Would you all feed it anyway? Also don't see any evidence of mold....just crumbly and powdery. The other bags I used did not look like this...corn, oats, etc were easily distinguishable.
