Keep in mind that a certain % of drones should be present in the hive, depending on the hive's resources. I don't know what the % is, so I tend to let the bees decide. Some folks I know kill any drones they see and destroy drone comb and drone cells. I only remove drone comb below the frames or if it gets really too abundant. Some beekeepers will do the sacrificial comb practice, which I think if you are designing your management system that way, it's a good thing. I did not have good success initially with my green drone frames, but will probably try again.
Banjos and bees... how sweet it is!
