Sounds like she just needs to get some stability in her life. She's been through a lot lately. When my birds get stressed, I give them extra treats such as red grapes, chopped raw corn-on-cob, or air-popped popcorn. The way I approach them is that I come out with a large feed bowl and shout, "Look what I've got!" They all know that catch phrase. No matter where they are, they all come running to greet me, and I spend some time talking to them and handing out treats. I think it's good therapy for them (and for me!).
BTW, welcome to BYC!
