The Giant Fat Ball Duo makes a delicious gourmet buffet for your birds. The two fat balls contain the same energy-rich ingredients, but one has an extra layer of specially selected, high oil content black sunflower seeds. The two fat balls are joined together with string and suspended by an integral string loop for easy use. Calories are hugely important for birds, particularly in cold weather, and the Giant Fat Ball Duo provides an instant refuelling station for your garden birds. Composition: Vegetable oil, wheat, black sunflower seeds, yellow millet, sorghum and chopped peanuts. Analytical constituents: crude protein 7,90%, crude fat 35.3%, crude fibre 2,7% raw ash 1.5%
