Okay, checking my favorite bee websites and people are starting to check their hives for losses. How do you do that? What does a dead bee look like versus a cold bee? At what temperature can you hear them buzzing in the hive? What other ways is there to check? I know that, as of now we have 1 hive that's kicking, can hear them and on warmer days, 30 deg+, they have been pushing the dead out. The other three have been quiet without much activity, but they were all different types of bees. It has been brutally cold and windy here for the last month and it's our first year, so I am looking to figure this out so that I can get over my pouting and adjust accordingly for this coming spring.
