Yesterday my neighbor and I checked our six hives. Four of them were egg-less, brood-less, and queen-less. Three of those still had lots of bees.
We'd like to figure out what happened, so we can avoid it next year, and so that the remaining hives don't suffer the same fate in a couple of weeks.
Can someone help with an inspection and analysis, sort of non-post postmortem?
