My husband found our bird in a pile of leaves in December and saved it from dying in the freezing cold. It has taken me this long to figure out what type of bird it is. I am feeding it a cockatiel & small bird mix. Is there something else it should be eating? Also it is eating or at least tearing up the grit covers I have on the plastic perches in the cage. I have never had a bird before and I hope I am giving it everything it needs. What else should I know about this type of bird. See my picture under rosella pictures. Thank you.

Rosella's like to chew so tree branches are a must. No plastic at all.
A rosella's diet should contain about 40% wild parrot mix with about 60% fruit and vegetables. Sometimes they may even eat small insects and/or meal worms - although mine haven't that I've seen.
Rosella's like to bath so a large bowl for daily baths is also needed.
They need a large cage as they have strong muscles that need plenty of exercise - 3 metre's long x 2 metre's wide should be sufficient.
They're not much for playing with toys but will occasionally bang a hanging bell.
