Cuttlebone is a hard brittle structure found inside cuttlefish. It is made mainly of calcium carbonate. The cuttlefish use it to control floating. Cuttlebones have been used to make polishing powder.
All birds need calcium, and cuttlebone is as good a source as any. Most of theparrots will willingly chew up a cuttlebone. Others, such as mynahs, toucans, etc., will not eat cuttlebone as it naturally occurs. In feeding these softbill species, it is just a matter of scraping cuttlebone into their soft-food mix.
Cuttlebone is an important dietary supplement for birds because it is a great source of necessary minerals and calcium, which helps birds with bone formation and blood clotting. Cuttlebone is an inexpensive source of calcium carbonate and other trace minerals for your bird.
