Even though Budgies are considered one of the easiest birds to care for, sometimes incorporating supplements to their diet is a necessity. Budgies often need extra nutrients, not found in greens and seed, in order to live in a tamed environment. Calcium blocks or Cuttlefish bones are the easiest way to provide your bird with much needed calcium. For a cheaper alternative, try grinding eggshells into a fine powder and mixing with your Budgie's feed. Grit is needed regularly for your bird to digest foods properly.
Grit acts as an internal grinder, milling foods down in the bird's stomach.
You can purchase commercially prepared grit or add loose sandy soil to your bird's food. You can also add a separate dish of grit to your bird's cage. Although Budgies can survive without water for up to three weeks, it's recommended that you provide your bird with fresh water daily. Your Budgie will not only drink his water, but use it for bathing purposes, as well. For this reason, your bird's water is often easily contaminated.
