Hi I have a 5yo cockatoo who keeps pacing and I was wondering if that was normal since I've had him for 4 days? Also, Henry when he's nice and calm we let him come up on us and he immediately goes up on our shoulder. He bit the side of my moms face close to her eye and he has bit my arm once. He doesn't show any signs that he will bite like squinting his eyes, fluffing his feathers or hissing. What do we do to get him to stop turning on us? I do understand we are still trying to know him and he's been passed on to a few homes but I don't want to give up on him this early. Thank you
