Hello and welcome Carrie! Sorry to hear about your loss of your grandmother, but happy that you will be able to take care of her bird! I just rehomed my TAG last year, so there are others here who can give you more advice about the cage. I can tell you that given plenty of time, Baby will adjust to a new home and new people. Knowing her history and having some idea about the care she received is a big plus. You aren't a total stranger, and you know she wasn't mistreated. Just give her time to adjust and learn to trust you and all will be well
