I am in Dutchess county New York about 15 mies east of the Hudson River. I wrapped my hives with high r board 1/2 insulation in November. All hives (6) appear to have made it through the winter and have consumed all 16 lbs of sugar patty that was placed on before I insulated them. I recently added 5 lbs of hard sugar patty to each hive since I felt was to early to start syrup. My question is at what point should I take insulation off 2 hives are extremely robust and I am afraid as soon as drones are present they will swarm. I have a feeling the warm hives might have started a population increase earlier than I was expecting, I also think that might have accounted for the amount of sugar they are consuming. Any thoughts are most appreciated.
