Are there queen cells in either/both hive? If the bees made queen cells, the virgins should have emerged 16 days later. After that, it takes time to mature the ovaries, take mating flights, and get the hang of laying eggs. You could be seeing eggs/larvae by now, or it could take another week or two. But if there were no queen cells made, both hives are in trouble now.
I'd take a close look to see if there are remnants of opened queen cells in each hive. What you want to see is at least one cell that is neatly opened at the bottom, indicating that a virgin queen emerged.
