welcome!! If she has had seven years of mistreatment (or neglect) don't expect that she will turn around in a month - but expect that with MUCH patience and love she WILL turn around. If she is in a small cage, I would suggest a large cage with at least three different perches (to relieve foot sores) and a few good toys - chew, forage and foot toys to start. Talk to her, read to her, offer her treats and try to remember that a year might seem like a long time to you, but to her it is more like a week.
Please let us know how it goes when you pick her up.
