I usually do queenright queenraising - essentially a Demaree with the brood above a couple of supers. It's always worked fine in the past. This year it didn't work in the hive I chose. So I moved the hive to one side, put the brood box from the top of the hive iin the place where the hive had been so as to allow the flyers to return to the, now, hopelessly queenless hive. it was now full of bees and with no prospect of raising it's own queens and with no queen pheromone.
A day later I brought a frame of open brood from my preferred breeder to the queenless hive to graft into the polished queencups. So far so good.

However as quickly as I put larva into the cups, the bees were removing them. Eventually I gave up and the next day found only three viable queencells.
Has anyone else seen such behaviour?
