I've moved your thread to the LOST sub-forum.
Members of Talk Budgies will see the thread when it is in the proper section of the forum.
It is important you contact as many people as possible to let them know to be on the lookout for your budgie.
The links JRS provided to you have all the information in them which you should be following at this time.
The more pro-active you are in searching for her and getting the word out the better the chances will be of you getting her back.
Good luck - please be sure to update us in this thread
