Both hive started from nucs in May. One hive has the bees hanging out in the front all the time Thought they were hot so I installed ventilated covers without inner top cover.
The one with the bees hanging out in the front has a lot of bees in the upper ventilated cover the other hive has no bees in upper cover.
They both consume a gallon of 1:1 sugar syrup every three days.
Should I be worried about the hive with the clustering in the front
