Bee-wildered

When wanting a new queens, have been having great success with OTS, what would you recommend for turning this into queen raising? How do you encourage mating these queens besides providing a cozy lit meal of comb, mead and Al Green

I am new to bee keeping, hive doing extremely well lots of brood, capped cells, pollen, larva various stages. Queen is a beauty laying fantastic all spring started seeing Queen cells so I pinched them off with hive tool.... good idea or should I have left them alone as the bees know better than I?

If one see queen cells in a thriving colony should they be destroyed or left as the bees know better than I?
