Brian, we had very good weather this last weekend. tee shirt and shorts! I would imagine your virgin had a chance to fly... if she found drones..hard to say? you still have some time yet. I would imagine if we had a few days 60 degrees (right now/ in the next 2 weeks), you would be OK. Would love to hear your results, either way...
I have not a lot of experience raising queens but have not had the best luck (w/ mating flights) before end of may into early june. When do you see the first swarms in your micro-climate? I have seen swarms end of april-1st week of may a few times but I always thought they were escaping packages or migratory bees.
A few of my hives are booming and have plenty of drones. The rest are very small clusters just starting to build up.
Cali bees nearby? Could be a good thing for once...
