Welcome, Lisa! Congratulations to our newest Too owner! Thank you for offering your heart and home to a needy too.
As psychocircus91 mentioned, it's usually better to move at the bird's pace. All birds are different and all adult birds have a past, most complete with baggage, some birds bounce back quickly and readily adapt to change, others are suspicious of everything and need time to build trust with a new human. If you have a shy, reluctant Too, try sitting in a chair near the cage and read aloud, sing or simply talk to your new friend, great way to bond.
Do you have experience with parrots? If so, carry on, if not, please do some reading about diet, cage set ups, toys and especially Toos, they can be a huge challenge for anyone. After the ordeal your Too has been through it would be helpful to have him checked by a certified Avian Vet, once he's been assessed, the vet can help by suggesting a healthy diet. Best of luck, please feel free to ask lots of questions.
