So I did a little experiment this spring. On May 6, I I removed the queen from a strong overwintered hive, plus two frames of emerging brood and relocated this this nuc to another yard, leaving my original hive to rear its own queen. I think I timed this ok, as I've seen hatched and capped drones and we were having good weather and flow(?...bees were working a lot and a lot of dandelion/ fruit bloom). I'd like to supplement the queenless hive with brood so that the bee population doesn't decrease drastically and eliminate my honey yield while the new queen matures, mates and starts laying. What would be a reasonable number of brood frames to give the hive every week or so? Would you suggest open brood (allowing the possibility of bees to raise a new queen in case of queen failure) or capped brood (not taking any resources to raise). Also, when would you suggest I start adding brood, keeping in mind that I'd like a brood break for mite control (the hive has been queenless for 1 week). Thanks!
