Like any animal, budgerigars need to follow a diet that provides all their nutritional requirements. Budgies are not fussy eaters, so the task is relatively simple. The bulk of their daily intake is seeds, a good helping of fresh foodstuff to make things more interesting for them and to avoid monotony, and a mineral block to fill in the nutritional gaps.
Budgies will happily feed from the ground
Having said budgies are not fussy, they will choose a yummier food such as millet or grapes (the favourite food depends on the individual bird) in preference to the standard seed mix, so make sure you get the balance right. If seed and mineral block are always available, and treats are an occasional extra, you won’t go far wrong.
