Straight shell-free sunflower chopped into medium sized pieces. A great no mess feed that is one of our cleanest options (only beaten by Coarse Sunflower and Premium No Waste). Not only are there no leftover shells, but by only offering one ingredient, you eliminate the incentive for birds to sort through the seeds to find their most preferred type. This means you go though the seed slower and have as little end up on the ground as possible. If you find that it is clumping up in your feeders when it gets wet, consider upgrading to either the Coarse Sunflower or Premium No Waste.
