Since every sunflower has all grades of sunflower seeds farmers will separate the grains from good to poor. Often the poor seeds are sold as “bird food” to discount box stores and discount seed makers. It can be deceiving because the outside of the shell appears normal to the untrained eye. Now you can see the difference using the link above to identify immature seed, blanks and insect damaged seed. The easy way to tell the difference is by a low advertised price. Click the link and ask yourself which grade of seed do you want in your feeder. Ironically, good seed costs priced only slightly more than poor seed but the food content is significantly greater in good seed. Since the seed often comes from grain brokers, the bags even look the same on the outside but the seed inside is quite different.
