KAYTEE® Sunflower Hearts & Chips Sunflower seeds attract more birds than any other grain. The hulls have been removed from KAYTEE Sunflower Hearts & Chips, making the seeds easier to eat and eliminating the mess hulls make under feeders. Fallen seeds will not germinate either, decreasing unwanted growth in your yard & flower beds. Sunflower seeds are highly nutritious and perfect for feeding year-round.
