I have tried to graft larvae three times now, and the bees only accept one cup. I think I may be hurting them in transfer. I have read about priming the cups with royal jelly, but how much is enough or too much? Also, I made my own grafting tool fron a paper clip, flattened, curved, and filed to a sliver. Is there a trick to scooping the little guys out of the cell, or does it just take practice? My homemade "jenter system" never works right, so I tried the old fashioned way. The colony split queens are working out really well, but I wanted to get into this grafting of larvae to queens. I read everything I can get my hands on, but I must be missing something...and they are fresh hatched larvae.
