The key ingredient in fat balls is suet, which is one of the most concentrated and easily metabolised energy foods for wild birds. It gives them instant energy, and they love it. None of Johnston & Jeff's fat balls contain cheap fillers and are formulated to be nutritionally correct, with a fat content of 18%. They are best fed from a Fat Ball Feeder but can also be placed on a bird table or ground feeder.
Composition:
Cereals, oils and fats, natural minerals and sunflower seeds.
