Cuttlefish bone, or cuttlebone, should be included as part of your budgie cage’s permanent set up. Clipped to the side of the cage, this provides a rich source of calcium, and will give your birds lots of pleasure as they slowly nibble and grind it away. Budgies need access to the soft side of the cuttlebone - the less smooth, inner side - otherwise their beaks won’t be able to break through the tough stuff.
