Petsupplyuk.com Standard Fat Balls for wild birds are made to appeal to a wide range of garden birds and to provide them with a concentrated and handy source of energy. They are manufactured from a range of locally sourced wheat, beef fat, corn and calcium specially selected to ensure your wild birds can obtain a high energy food source throughout the year. In Winter wild birds can rapidly starve if natural food sources become unavailable or scarce, in Spring and early Summer the demands of breeding and raising young place a great burden on adult birds, and during Autumn many wild birds shed their feathers, or moult, and this requires large amounts of energy. We suggest you place these fat balls in a specialist feeder and hang from a convenient branch, bird table or feeding station where you can observe a range of wild birds feeding safely. Alternatively you might try placing them whole or broken up directly on the ground or on bird tables or added to other foods for an added energy boost.
