Is this pic where the egg WAS before you moved it?
I personally would wait to see if she lays another egg, which she should and then I would discard both eggs and the nest and gently ask her to go somewhere else to nest. If you don't want her in your room (I don't blame you really)........the ledge doesn't sound like an ideal place for babies.
IMO, it would be best to do away with the whole thing and let her move to a safer place.
