It's very foolish to raise queens and to not take care about the drones.
If you raise not more than 20 queens a week during the swarming season probably you may not bother about the drones, but after that the mating success will be poor.
The virgins literally suck out the available drones from the area, so better don't rely to the neighbour's drones.
The simpliest way to raise drones is to put empty drone comb (but only one) from the previous year( or, if you don't have ones, let the bees to draw the drone comb by themselfves, but this delay the drone rearing process) into the lower brood chamber (if you, like me, use two brood chambers).
The drone frame MUST not be in the middle. The best is - next to the near/far frame.
Take care to be present in the drone collony lots of polen and continious income of nectar (or feeding) at any time of the season. When the drone rearing stops, nothing can't force the queen to start laying drone eggs again, so be cautious. Keep the drone colony strong, add brood if necessary.
Late of the season you can make drone nursing collonies. Collect the emerging (or sealed) drone brood from the drone collonies and place them in freshly made collony between brood frames and add 2 frames with pollen and 1 or 2 frames with honey. Put virgin queen (or queencel) in a cage. Feeding is advisable.
Use the nursing collony only once.
Never use only a one drone collony. It's better to have a dozen of them, it provides the necessary diversity for the proper functioning of the collony. And you never know wich queen will produce the best drones.
The size of the frames matters. For some reason i couldn't force the queens in shallow frames to lay eggs in the drone comb. With langstroth frame i don't have those problems.
If you put a queen on an ice cube just for few minutes, she will become a drone layer. I do not recomend it, becauce it that case you turn permanently some of your best queens into drone layers and they can not be used for breeding after that.
Try to avoid chemicals treatments during drone and (queen) rearing. If you use chemicals, the treatments must be done before the drone rearing starts, to keep the varroa mites under control.
The drone rearing is much more tricky, than queen rearing.
