Ohhhh how fun, 2 little girlies visiting
I've also heard that budgies like hanging leafy greens, but my guys have always been scared of stuff like that

So if they're not used to it they might be scared too, or maybe just try small pieces of hanging leafy greens and see how they take to it.
My budgies love broccoli, green peas, black eyed peas, brown rice, corn, a little sweet potato. Those are the faves, and I'm trying to work new stuff in.
Did you have any luck getting them to come out and fly? After a day or two they may feel comfortable enough to venture out.
