Minerals & Calcium Blocks / Cuttlebones
My recommendation is to only provide the plain calcium / mineral blocks. Stay away from flavored and colored items as they are likely to contain artificial flavorings / colors and harmful preservatives.
Cuttlebone provides calcium,iron and other trace minerals. Something that should always be supplemented. Cuttlebone helps keep your pet's beak trim, healthy and in good working order. If your bird doesn't start "snacking" on it, please scrape a bit of your pet's food, ideally mixing it in with soft / fresh food items.
Alternatively, don't discard the shells of your hard-boiled eggs. They are a great free calcium source for your birds. You can feed it to your birds ground up and it will prevent calcium deficiencies just as well as bought options / supplements. Hardboiled eggs together with the shell -- all smashed together -- represent a healthy and very much appreciated treat.
Below are some good options. I didn't even list the colored versions that are available nowadays. They are over-priced and contain questionable ingredients that have the potential of being detrimental to your bird's health.
