Lillebro Fat Balls contain a mix of grain & dried fruit which provides wild birds with important minerals & helps to build up their energy reserves. The fat, including the fat in sunflower seeds, is also an important part of their diet & helps them to stay healthy during the long, cold winter. Fat balls are very popular but they are particularly important when temperatures fall below zero or when everything is covered in snow. This kind of weather makes it difficult for birds to find food naturally, so it is a good time to put out some fat balls. The wild birds in your garden will be delighted. Lillebro fat balls are made with care & tested for ragweed seed (ambrosia artemisiifolia).
