Hi, Opened the rubbermaid container yesterday to feed ducks/geese and the hen scratch had all these black bugs in it. Are these weavils or what? We sprayed around the container to keep ants and such away. But these bugs have came out of nowhere it seems. I know birds eat bugs and stuff but will eating these hurt anything? The grain didn't have any bugs until yesterday. I have some cracked corn for them to eat until I get to feed store. Thanks!
