If you have a laying worker and other hives, putting a frame of brood from one of the other hives, or a frame from each, will help keep the population up, possible cause the bees to make queen cells, and/or make it easier to introduce a new queen. A frame of brood can't be beat when refurbing a LW hive. Too late in the year to let them do their own, so keeping the hive going and more acceptable to a queen is important.
