Well with the warmer weather in the Chicago area today being around 50 degrees I saw a lot of activity with my hives in the afternoon, but I noticed two of them there was nothing. I already assumed the worst and when I popped the tops not a bee walking around in the two hives. I will do a full inspection tomorrow to figure out the reason. So far I got two double deep hives still kicking and my Palmer style double nucs doing fine. If the remaining hives make it until spring I will move my nuc hives to the full size hives and be back in business for the spring. One lesson learned is having those nuc hives as backups is highly recommended to cover for losses because you just never know when a hive will bite the dust. I'm already planning to have another pair of double nucs for next year. I rather have over wintered nucs then buying packages with questionable queens in the spring.
