Welcome!! I agree, patience is your new favorite word. A couple of weeks to us seems like a long time -to a Grey that would seem like a couple of hours. They (or I should say, some) take a long time to learn to trust another person. Shadow's story doesn't seem as bad as some, but you still have a bird who doesn't interact well, simply because she hasn't been given the chance. Take your time, talk to her as much as possible. Always keep an even voice, even when you get bit. And she most likely will bite. Put her back in her cage as you tell her how wrong biting is. Hopefully you won't get any real bad ones. LOL I think you will do fine. Simple foraging toys can be treats or toys in a brown sandwich bag. If she isn't use to having them the bags are a good way to start. Make sure she sees what you are doing and don't close them to tightly - she will pick up the idea pretty fast. When she gets the idea you might want to buy a couple to push her ability.
