The easiest way to raise your own queens is to remove the queen from your best hive(start a nuc with her) and then after the hive builds and caps the queen cells in the hive, you would take them out and place them into their own nucs to hatch and mate. This works for small numbers of queens.
Another way is to catch your hives before they swarm(but after they have started swarm cells) and remove the queen cells to their own nucs to hatch and mate.
