I was adding honey supers last Wednesday everything was looking good. They were plugging honey away like mad. Filled a deep and a medium in a week. I go out tonight to see if they had filled the the medium I added Wednesday to find three hives had swarmed. There is still bees but the numbers are way down. I don't get it? They have lots of room to lay. Just when I think I might be catching on something like this happens. It's frustrating!! We have had some hot weather the last 4 days, could that be it?
Also I did 8 splits in the spring. They are doing well but I can't get them to expand out. They want to go up!any suggestions?
