Vance, this is all new to me. It was 27 this morning with a heavy frost, around 50 mid day - and I thought my bees were being robbed. (package last June) So I went over there to check them out and it was a combination of some things. Orientation for one, but the bees were bringing in a ton of pollen! We've had several nights in the twenties and our first frost was about a month ago, plus we've had plenty of frosts since then. There shouldn't be any pollen anywhere. I studied them for a while and didn't see any fighting. I fed them two quarts and a pint about two weeks ago. Their stores were in very good shape last October. Now (rookie fever) I'm thinking - if this keeps up they'll swarm. I want to slip them another quart or two but now I don't know.
