JW - you pose an interest logistics question. For each queen to be raised, you need supporting resources at least temporarily. To keep her going, she needs to have a hive. As I understand your statement, you are going to need a hive (or a hive in sections) per queen. A nuc per queen would be too small . Correct? - MikeMy idea of vacation is putting my wife's luggage in the car and me staying home to play with the bees. Seriously, you need to get your priorities in order.
But back to the solstice, now is the time to be making queens for next year's production hives. There is a strong belief that queens mated after the summer soltice will be the best producers. I read it on the internet so I know it is true.
