This is my first year grafting and rearing queens. That being said, I have ~20 hives and I am torn as to what type of mating nucs I will use. If I graft 20 queens at a time, what would the best option for me? Not sure I have enough resources, bee-wise, to make 20 5F Nucs for mating nucs. Would 2F mating nucs be an option? Thanks in advance!
