I have two hives, one clearly weaker than the other. Today there is a frenetic amount of activity at the entrance of the weaker hive. Seems like it could be robbing going on - however I notice the bees are carrying a lot of pollen: both In and Out of the hive.
If a hive is being robbed would its bees bother bringing in pollen? Or maybe the robbers are so greedy they are leaving with pollen, but going back in for me or for some honey too?
