I'm glad she made it :)
Unfortunately, hens can be eggbound whether they have been eggbound before or not :/
I just suggest giving her a human calcium tablet once a day for a few days after this just to make sure her shells are back to normal.
Are you sure that she is eggbound? Put a glove on and put lubricating jelly on it, stick your finger a few inches up her vent, and if you don't feel it, it might be another problem.
