I was in a local feed wholesale store not long ago when a guy was on the phone trying to find large bags of popcorn. When he got off the phone and realized I was listening in he explained that a Cuban man had come in and wanted the popcorn to feed to his "sporting birds." I'm pretty sure what he meant but I just didn't see the logic in the popcorn. I was wondering if anyone might know the difference between standard corn and popcorn as a feed?
