Why is he eating that?

[Sulphiria]

My grey recently started eating pistachio shells and paper. Needless to say he doesnt get either now. Is there a reason for this?

Dont have to be a reason, just a bad habbit. But there is some theori that there could be some lack of vitami or minerals so check that he/she is getting the right food

Is he just shredding them? They can be doing it for fun, look at it this way, it helps to trim their beak to chew on hard shell.

He will shred newspaper and cardboard. But i gave him construction paper and he was swallowing it, same with the shells. So hes not getting either now. He gets fresh fruit and veggies daily, and he eats it. Today was snow peas, apple, cantaloupe, and green beans. Plus he gets pellets that he eats.

It sound great so this could just be a bad habbit
