Give it a few days, talk softly around the bird, maybe sing it lullabyes. After 2-3 days of this, gently open the cage door and lower it a few times in the day, while singing/talking. After a few more days, poke your finger into the cage a few centimeters. Now more than a week has passed. She'll still be afraid! But now your voice and the door are less worrisome than The Scary Finger. After 4-5 days of finger, try softly stroking her breast. If she nips you, go back to just poking it in for a few more days. Eventually, you'll be able to press your finger parallel to her breast and she'll climb on for a second. That's progress! After a bit more, you'll be able to remove her from the cage. Be patient!
1st: It's spelled Buddy! (at least in the U.S.)<br />
2nd: Stealing a Baby away from her Parents is called Kidnapping.<br />
3rd: Of course she's scared! She wants her Mommy, you have her locked in a Cage.<br />
4th: She'll probably not even get used to you before the F.B.I. watches the security tapes, figures out who you are, drags you away, and tosses your *** into Prison forever!
just play with her
No budgies are daft. They don;t like to be alone so put a couple of mirrors in the cage,
Just keep talking to it then.
Tbh there isn't much you can do...just time will tell how she/he will respond to you
