They say if you give laying workers a frame of open brood once a week for 3 weeks it will often solve itself and raise a queen. If you have drones around it may or may not work.
My own opinion is that is a waste. 3 frames of brood is a nuc, don’t waste it by mixing with a laying worker colony. We don’t even try rescue a lw colony, I will shake them out and move on before they wreck a pile of good comb by raising drones in it.
