... Question when in N.C. should we start making Queen's. Sorry neil should have started new post.
Sorry Neil, I'll take a stab at the answer here before we get back to the OP.
Not sure whether your question is 'when will drones be mature enough for mating' or 'when local queen mating weather will arrive in your area'? If you are asking about drone maturity, Tecumseh showed me how to touch the thorax of a drone and lightly push it down to the comb...If he buzzes, he is mature enough to mate. I believe queens prefer to fly in temperatures between 70-90 F.
Of course, there are mating flights outside that range, but that range is optimal. We had queen cells hatching in a NUC on 7 JAN this year, no brood or eggs or queen visible...yet on 23 JAN, there was a laying queen with a small circle of capped worker brood present. We have had a mild winter, so, you never know.
