I installed two packages 23 days ago and from the moment that I walked away from the hives, I could tell there was a difference.
One hive was quiet (like you described) and the other was very busy. Activity from the quiet hive but significantly less than the "busy" hive. When I inspect the hives, everything appears to be fine with eggs, larvae, and brood in both. Both hives were drawing the comb out equally until this past week. I noticed that the quiet hive had drawn 9-9 1/2 frames out (busy hive about 8 frames) and had used twice as much of the 1:1 syrup than the busy hive. I'm using gallon jars over the center hole in the inner cover.
Soooo.............I wouldn't worry. Based upon my observations, the quiet hive has just been busier inside of the hive instead of goofing off outside of the hive! Just my rookie thoughts!
