Oh yes......its far from over, and I am both amused and horrified at the folk being fired up enough to go through broodnest this early, and even claiming they are into expansion and already with new seasons drones. What are they looking for? Why? What can they do about it anyway?
Sounds like a high peeing competition to me. One that is amusing to most experienced folks.
Bees flying strongly at 5 and 6 C? Unless its a cleansing flight or orientation then I don't want that kind of bee....lots of flying about for little gain, accelerated burn out, and management difficulties to follow. I have some very black local bees, and even they don't waste much time and effort when there is little to get.
