I installed two package bee sets into their hives yesterday and am seeing a huge difference in activity between the two hives. one has about two dozen bees in and around the entrance at any given time while the other has periods of time with nothing coming in or out. I have noticed both hives do have bees bringing in pollen already. but my concern is the lack of activity in the second hive. Is this normal? could have the bees from the second hive grouped with the first hive?
