I think my hive may have died. I am in Maine, up until recently we have had a fairly mild winter. Over the last couple weeks we have had a few storms..A little over a week ago we had a freak rain storm, a lot of water in a short period of time with heavy winds. I checked on my hive the next day and replaced the homosote board that I place between my inner and outer cover to absorb moisture. I could hear the hive buzzing. The next night we had a freeze then a couple snow storms. I checked the hive (did not open it) no buzzing. I am a new beekeeper and this is my first winter.. Any northern beekeepers have any advice? Am I just paranoid?
