Here is a crazy question. I have a yard of 7 hives, but one hive is monstrous with huge amounts of bees, probably two or three times the quantity that is found in any of the other 6 hives. Today, it hit about 55-60 and the girls were flying and roaring with their buzz. I am sure that these girls are robbing the other 6 hives and I have entrance reducers on all of them. They are bringing in Pollen or something like Pollin. Some of the bees look like that fell into a bin as they are brightly colored in orange/yellow dust. Within this hive, they are still in a loose Cluster mass and have now reached the spare sugar that I placed onto their frames. I am reluctant to split them but I am concerned enough that they might even swarm on me. Will they swarm if there is no nectar flow and what temperature should I split them?
