Dakota is stunning! He sounds like he's going to adjust very well to His new home and you.

I read tiels poop on average every 20 minutes... so, a little over, a little under, it's fine.

The humping might be his normal behavior, or could be the changes in his life, testing the new cage, a little self-comfort.. Wait and see. I think he's gonna be a spunky little outgoing guy.

I love him! Congratulations, and Happy New Year to you and Dakota!
