Laying worker hives don't always mean multiple eggs per cell. That can be the work of a newer queen also. The key thing to look for in a laying worker hive is that the eggs are NOT in the center of the cell but instead on the walls or even the corners of the cells. Were you able to find your Queen in this hive? If not and the eggs were NOT in the centers of the cells, I'd suspect laying workers, however if the queen was there, she may just be a new queen. Give her an extra week and check again in that case.
However, if you find that it's a laying worker hive, the best way i've found to fix it is a shake out and rebuild with another hive nuc and let them queen theirself.
