Not necessarily, I would make her a laying bin within the next hour and give her privacy and with any luck she'll lay. Is she in good shape? If she's still acting alert and generally healthy there's a good chance she'll lay them by herself. It'll help her out if you pre-make a tunnel in her bin once you have it set up - she may just take the short-cut and use your tunnel instead of making a new one herself.
Good luck!
