Hope this hasnt been covered a million times. Is it at all likely that a new split that just contains brood, nurse bees, and a queen would swarm? Why would they disappear and abandon brood? Would a change in sun exposure (to more sun than they had) upset them? I was thinking that nurse bees wouldnt support a swarm. All the foragers apparently went back home to the original hive, and the nuc looked OK but lots of bees hanging out on the porch. Then gone.
THanks!
