I am a mentally challenged, novice beekeeper, but there is one thing that I have learned. It's that each hive has its own personality. In one of my apiaries, I have two hives that are three feet apart and their queens came from the same supplier. One hive loves patties, and the other hive does not pay attention to them. One hive flies in much colder temps and in greater numbers, and one hive is nice tempered and the other hive has the demeanor of an enraged communist.
Some bees are not drawn to fondant and patties as much as others. I realize that some of this may be due to the needs of each hive, but I also think bee hives have differing personalities just as do individual people.
