Hi, I'm Nicki and I live in Gunnison Colorado. I have been a beekeeper for 5 years and I live in subzero temps. My current hive has made for 3 years in subzero (-20 at nights) I have not had troubles at all. Until today, I went outside by the hive and started seeing frozen bees everywhere in the snow. We have not had warm weather definitely not anywhere 50 degrees. It looks like they went in all directions and froze. It also looks like they pooped ( we have snow on the ground so you can easily see them and the poop) right before they died. The circle of carnage is up to above 12 yards for the hive. Any ideas why he change in behavior from past years? Or why they would just leave?
