The key ingredient in these High Energy Fat Balls in suet. Suet is a pure refined animal or vegetable fat and is one of the most concentrated and easily metabolised energy foods for wild birds.
It`s a superb all-year-round food, and can even cope with hard frost. Johnston & Jeff High Energy Fat Balls are made using a tried and tested recipe and to the same high standards as their wild bird food mixtures. The only other ingredients are cereals and seeds.
