Congrats on your new baby!
She's just scared right now. She just moved for the first time in her life and things are so different from what she knew before. Sounds, smells, people and the environment has changed. She just needs time to soak it all in. Just like people, birds are individuals. Some are friendly, but more shy and need time to warm up.
Go slow with her while she us adjusting to her new home. Feed her treats without picking her up or just talk to her softly. Wait to pick her up for awhile, but let her spend time out of the cage. Maybe only pick her up when you need to put her back in. I bet you will see a huge difference in a few days.
A lot of people talk about clicker training. I will let them respond about that. It seems to work well.
