One hive (hive 2) consumed the sugar water with thymol and two hives did not touch the stuff. The two hives (hives 1 and 4) that are not consuming any sugar water were formerly given frames of honey from the deceased hives. I am continuing to feed hive 2 sugar water without thymol.
We have taken all sugar water away from the front of hive 1 and put on supers since it is so active. We peeked inside after seeing a lot of bees out front and saw that all ten frames were full of bees. This hive has been active at cooler temperatures then the other two hives since early in January. Earlier inspections showed empty frames that were not all the way drawn out in the top deep box. (A drawn out frame is one on which the bees have made wax cells.) It would be nice to prevent swarming in this box but on the other hand, it would be nice to perpetuate this queen bee's genetics since the hive is so vigorous at lower temperatures. We need to watch for queen cells and make a hive split if we spot them.
