I have a nuc that I started about the first of July with a purchased queen. they are doing well at building up and storing food. I went in today to look at them, and they were all just running around on the frames in a sort if frenzied way. the queen is there--I saw her, and there are no queen cells. the bees don't seem to be abnormally aggressive. everything I have read about "runny" bees is an association with aggression. is runny-ness just another normal trait, or do I have a ferocious hive to look forward to when they get more populous? I haven't seen bees behave this way before and I'm in that dreaded third year of beekeeping that keeps reminding me how much I don't know.
