Hi Sunshine, Welcome to our Family! Julie & Dan have obviously given great advice and I would like to share my version of "rescue". I had a cockatiel which I "rescued" when he was 1½ - already cage bound, already not tamed. I had him for 17½ years and during this time the only "proper" hand contact I had with him was in his last days when he was very poorly. He never tamed, but did come out of his cage - but it was a battle getting him back in and unfortunately used to normally end in me "towelling" him to get him back in. To be honest, Spiky was happy in his cage - and in the last few years if I opened his door, he wouldn't come out
You have to decide what you really want in a grey - do you want that "talkie, cutie" that you've seen on YouTube, or do you want to give a loving home to a bird in need of a new home?
You ask as many questions as you like - it's best to ask than to guess! Looking forward to hearing how things went - best of luck xx
