Sorry you lost the swarm John.
I tried using conventional A/S as part of swarm management and couldn't get along with it so on recommendation from a long standing beekeeper, I began to remove the laying Q in a Nuc along with a frame or two of bees and brood, leaving a single viable queen cell in the "parent" colony. This works well but necessitates moving Nucs to another apiary and creates additional stocks to inspect....
In preparation for scaling up the amount of queen rearing I do, I have read a fair bit about Wilkinson & Brown's Queen Right Queen rearing method and use of Cloake Boards etc. and as a result of my background reading (this forum included) I have introduced the Demaree method of swarm management into my apiary management and currently prefer it over a conventional A/S.
