I put a spacer on top of my hive as I am feeding pollen patties and treating with spearmint or something and I was squishing bees everytime I closed the top. Now when I open the top there is a baseball size clump of bees hanging from the top and a bunch of them fly up when the top is removed. I haven't been stung but it is disconcerting to have them flying aroudn! I would think they should be down working on storing or drawing comb, not lolligagging on top.
Your thoughts are appreciated!
