Poor Budgie! The person who let the budgie get into that condition in the first place should be ashamed of themselves! The bird would have to be syringe fed as there's no way she'd be able to crack seeds!
The person who let the bird get to that state should be prosecuted. Poor little thing. Sky's beak has gone nuts and is growing too long and I have to have it cut every 4 weeks but how could anyone not notice the bird was having diffuculties way before it got to this stage.
