This is our premium blend that changes slightly with the seasons. During the winter months, we add more millet for the increase in ground feeding birds like Juncos. In the spring and summer, we add calcium to help strengthen the nesting birds when laying their eggs. Offer our seasonal blend and attract a wide range of bird to your feeders, no cheap fillers! Ingredients: Black Oil Sunflower, Peanut Pick-outs, Hulled Sunflower, White Prosso Millet & Calcium.
