My Java Sparrow's have a constant supply of minerals and trace elements, I give them Pick Bloc from Orlux (subsidiary of Versele-Laga).

It's very similar to traditional pickstones but comes granulized as oppose to a solid block. It has a balanced combination of sea corals and redstone that are rich in mineral content such as Iodine, Calcium, Phosphorous and Sodium.

Pick Bloc is on offer to my Java's 365 days a year and is devoured. I put fresh amounts out daily and it's gone within minutes. I'm inclined to suggest that this may be the favoured grit consumed by my birds due to the frequency of replenishment.

Charcoal

Once a week I offer my Java's charcoal.

I'm not too sure on the mineral properties that charcoal has to offer but it's a great supplement to aid healthy digestion.

It works wonders if a bird is experiencing digestive problems, such as constipation or very wet droppings.

Charcoal passes through a bird's gut and absorbs excess quantities of toxins and gases.
