Hello, I'm a one year beekeeper. I had a great start with a nuc last spring. Summer was great. I harvested one super of honey and all was great. Left two deeps and a super full of honey for the winter. I live in CO and we can have some rough weather, but often have warm days. As a new bee mom, I insulated my hive with foamobard. I went out to show my setup new years weekend and my hive was silent!!! i cracked it open and all my bees were gone. There were about 500 dead bees, but otherwise I was left with a hive FULL of honey and no live bees. What happened? Did they overheat and move out? Now I'm left with a full hive of honey. Should I just harvest it and start over in the spring? Any advice appreciated.
