So our bees died this summer, Chris talked some kind of expert (maybe an apiarist?), and based on the fact that there was still substantial amounts of capped honey left in the hive, and there wasn't any evidence of foulbrood or other major pathogens/pests, we think they froze to death. I put some more pictures on facebook. If you want to see our new bees, we're having workday tomorrow April 10 after noon, and Saturday, April 11 for most of the day.
