yesterday I drove by my big hive on the tractor I was a bit surprized to see a humongous number of bees flying around the entrance I am going to inspect them in the next couple of days but I haven't been in it in about two or three weeks, there is always a lot of activity but this was much more should this tell me something?
Either they are hauling in nectar like not tomorrow, or you stumbled across at exactly when the young bees were orienting, or they are bing robbed.
I bet it was orientation flights. there must be a huge number of bees in there I think I will see if they have made any more honey saturday I might better put another super onthey were not being robbed they are the only full hive I have, and there were none of them looking for other ways to get in
