Johnston & Jeff Fat Ball Fat Snax 6pk

The key ingredient in fat balls is suet. Suet is pure refined animal or vegetable fat and is one of the most concentrated and easily metabolised energy foods for wild birds. It gives them instant vigour, and they love it. It's a superb all-year-round food, and can even cope with hard frost.

Fat balls should be fed in addition to other foods - they provide much needed energy for the birds and are an acceptable substitute for insect protein, which is lacking from a wild bird's diet in winter. Fledglings in particular need insect protein for healthy growth and development, so it is important to continue feeding fat balls all year round.
