So I have a problem. Been grafting queen cells and 90% of the time I get 17/18. Haven’t tried to put a graft of more than than in a hive because I ve read that due to resources, all the grafts won’t take. That’s been born out of my observations as well. My problem is this: as soon as we get to the capping stage, every time the bees start tearing down the queen cells until there is only 3-6 cells left in the hive. Things that I’ve tried: starter/ finisher hive. Finisher hive both queen right ( moved up open brood, moved up capped brood) with queen under excluder. Tried queenless finisher hive with nurse bees, capped and uncapped brood. Tried cell starter, cell builder, and cell finisher hives. Tried cloake board method. Shook in enough bees that finisher hives were near swarming conditions. Still are getting the queen cells culled to about 6 cells. In desperation, I’ve bought an incubator to put capped cells into as soon as they’ve been capped. Still trying incubator method with roll cages. It’s still puzzling that I checked finisher hive yesterday ( day before capping according to queen math) and had 17/18 beautiful queen cells with only 4 left to cap. Checked today, and the hive has already torn down three queen cells, with two still uncapped. I’ve moved to capped to the incubator ( first time trying this) and left the others to finish capping. My big question. Why do the hives keep tearing down my queen cells right at the critical capping time? I’ve stuffed the hives with bees, feed and pollen frames so it’s not a question of resources. I should say I’m using the nicot method because my direct grafting does have as high as an acceptance rate. Any help is appreciated.
