Shell

Hi, im new to the grey world and no amount of reading would have actually prepared me to owning one, and the mixed do's and donts from it all, my african grey (grady) is 2yrs old, her cage is a large cage situated in our living room, 1st question i have is do i try to interact with her straight away etc as was told to just leave her in her cage for at least 2 weeks, she takes food gently out of my hand but when i try anything else bites, she doesnt have her wings clipped and we did let her out of her cage for a fly around tonight, but when my hand went near her she bite me again, should i or shouldnt i be doing anything? And advice greatfully received
