Key Buying Factors
Natural cuttlebone
Cuttlebone is a natural, accessible calcium source that birds nibble at will, also helping keep the beak trim. It is the classic, safe way to provide calcium in the cage.
Form and accessibility
Calcium comes as whole cuttlebone, crushed, or in mineral blocks, so choose a form your bird will use and that suits its size. Accessible calcium the bird actually uses is what matters.
For laying hens
Laying hens need extra calcium to form eggshells and can suffer deficiency without it, so calcium is especially important for breeding or egg-laying birds. Provide ample calcium for laying females.
Balanced diet
Calcium supplements work alongside a balanced diet, since a good pellet-based diet with fresh foods also provides nutrients. Supplements fill gaps rather than replacing good nutrition.
Vitamin D and sunlight
Birds need vitamin D to use calcium, which comes from proper UV light or sunlight, so calcium and D work together. Consider UV lighting for indoor birds alongside calcium.
Veterinary advice
For laying problems, suspected deficiency or a sick bird, consult an avian vet, since calcium issues can be serious. Supplements support health, but veterinary guidance is important for problems.
