Thank you very much for the reply.
He is like 5 moths old, and he came home 3 weeks ago. He steps up, I can touch him all over the body including under the wings

When I put my hand and call him, he comes and steps up
Sorry I write he and him, but really I don't know if Sami is a he.
Well thanks for the answer, he is very curious and playful but when he is in or at the top of the cage, he becomes agressive...
