it works every time if you do it correctly. the key to raising queens is the starter not how you get the laval there. make the starter correctly any you will get queen cells. i also use the jenter and it works fine too. try using a cloak board on a really strong hive and you will get fine queen cells.If not in a good flow, then feeder needs be used on the queen mother hive, otherwise they will abandon eggs and larva, or eat them, in the cell cage. The cell starter hive must be strong and fed and desperately hopeless, just like in any queen rearing system.
So we filled all of the cups in the nicot box that we put the queen in. Then we moved only the ones with eggs into the frame. I have frame with 2 rows of 16. We only did 20 of the 32 since we did not have enough cups with eggs. Was that wrong.?Did you load all the cell cups? If not that is why.
