Kevin,
I can't express how much I appreciate the time and effort that you put into your podcasts. I started beekeeping in 2012, which I think is about when you started your podcasts, and I have listened to all of them over the years. It's always a treat when I see a new podcast on my I-phone and I will listen to it at the next opportunity while traveling in my car with my work. Listening today I enjoyed hearing about your discovery of a surviving cluster in a hive that was not flying like the others on a recent warm day. I have six hives that I am trying to get through the winter, but only five of them were flying during the few 50 degree days we have had since the hard freeze over the holidays. We had a couple of 60 degree days last week and on the second 60 degree day the sixth hive was flying like the rest of them. I was assuming that that hive was killed by the cold and thought this activity was probably just the other hives robbing it out, but your story has given me some hope that that hive was just on a different schedule for breaking cluster for some reason. We'll see come Spring when I can do an inspection. Keep up the good work.
