Have been sent a pic by a family member of a hive of mine (apiary is 1.5 hours away) with a cluster of bees hanging from the bottom of the landing board and front of the hive. I last checked them on Thursday but could not do a full inspection because of the low temps. I did see that the Super was filling up nicely and I was going to add another on Tuesday. I too a peek underneath and couldn’t see any queen cells. I would upload a pic but can’t see how to.
How big a cluster?
