I have started two new hives which are Italians bees and the Queen is a Buckfast queen. The queens are laying a good brood pattern. My question is when I add another half gallon of sugar syrup, there is lots more activity at the entrance of each hive. Seem like that robber bees are coming in but there is no fighting at the entrances. Do bees load up with sugar syrup, leave the hive and then come back to place the sugar nectar in the storage cells? I see lots of bees with pollen on their back legs going in too. I know is going to be very productive next year if things go as they are now. This my first time trying the Buckfast Queens. All answers will help me learn more about THE WONDER WORLD OF BEEKEEPING as a hobby. Mark F. Almond Concord, NC
