I use Pierco drone frames and think they work great. The Drones need to be 10 days old to be mature, and they take 24 days from the lay of the egg to hatch so 34 days from the laying of drone eggs you'll have mature drones looking for virgins. starting a drone comb once a week then transferring that comb to a drone colony is a good strategy. As you transfer in a drone comb to a drone colony, also transfer in a frame of hatching brood is a good idea. also transfer in a frame of nectar helps if you can, and keep a feeder on it.
Queens take 16 +/- 1 days depending on temps to hatch from the laying of the egg, and another 4 to 10 days to fly for mating, and usually are laying within 14 days from hatching. Sometimes they take longer, but in my experience, the best queens are mated and laying within 14 days of hatching.
I myself start the queen rearing system 1 week after the laying of drone eggs.
