You may change frames so that give brood frame from another hive and give empty frame to egg laying hive. If bees start to make queen cells, it has not queen.
So it is better to put packages together and you get really good hive. Do not raise own queen because it takes too much time.
Later when your big hive becomes large, you may get a new queen and make a nuc. When you join 2 packages, soon you have 4 boxes bees.
