I am an apprentice beekeeper at an apiary in Michigan---I was wondering if someone could take me through their method of determining a hives strength. What are the most important aspects you look for besides a laying queen? Also, when I open a hive I sometimes see a dramatically different attitude in bees from different hives. For example, I will see lots of activity outside of one hive, with foragers coming and going and when I open the hive they are all rapidly working---Looking at another hive from the outside I see little activity coming and going and when I open the hive all the bees are moving really slow. I am curious to know what's going on because in the two hives I just mentioned as examples they both have about the same number of bees and they both have brood and a laying queen. Why is one so loud and busy while one is lethargic and quiet? Thanks
