After over 30 years I am getting back into Bees here in Newton, NC. I have a new hive (one week). Package installed, queen cage removed, using a top feeder. Today, while watching the bees, I saw a very large bee land on the board and enter the hive. Could this be just a big bee or a 'wild' queen? Could I have a problem brewing? also, I noticed that very few bees are landing loaded down with nectar. Of course, there are not many flowers around now. We do have Bradford Pear Trees around.
