Hi, hope things have improved with Kiwi. My baby was the same for the first week but things are great now it just takes a little time. Once she realises that she can trust you,then you will be her best friend for life.
I remember when i went to pick Vera up and she bite the man in the pet shop he tapped her in the face, i couldn't believe it. When i got her home if she bite me (which she did most of the time for the first few days) i just said no and put her stright back on her perch in her cage and walked away, i would leave her a couple of minutes and then go back to her. She soon realised i am her friend and i am not going to hurt her and now i have the most loving best friend.
