Complete diets are formulated to provide all the necessary nutrients, vitamins and minerals to keep your pet bird in prime condition. Complete diets are a healthy mixture of ingredients ground up and baked at a low heath to form a pellet. Pellets come in different sizes, shapes and colours. You can choose your complete diet from a selection of well-known companies such as Harrison's, ZuPreem, Kaytee, Pretty Bird and Tropican by Hagen. When choosing a diet for your bird always choose what is best based on the ingredients in the diet and their quality. Organic is always the best. Very often Avian Vets will recommend complete diets for birds who have been on a bad diet over a long period.
