I clip and mark my queens and keep good records.
Can someone explain.........
Sunday PM
I saw mass of bees on outside of hive... ( double brood and supered) since it was one of the colonies from a swarm collected last season that I maintain to provide young bees for apidea, I allowed it to progress.
I observed the bees readying to swarm, excitedly flying in front of and around the hive... and then as one, fly off to a gatepost, from where I gathered up the bees into a nuc, found and caged a virgin queen ( must go and let her out if they have not eaten the candy already and released her).
The main hive colony seemed to have calmed down.
On inspection I found the original ( green marked and cliped) queen... a number of swarm cells sealed with one tuliped... and new eggs and brood of all stages.
I split the colony into 3, 6 framed nuc boxes, keeping back 4 fully drawn but empty frames ( gold dust!)
Have these bees not read the books?
By definition I caught a cast.... but this leaves ONLY after the prime swarm has left.
Weather is VERY changeable here.... perhaps that is the problem???
