In the last week I have lost two of my four remaining hives. Upon inspection, I found bees buried to the bottom of the cells with a small cluster of bees over them like they had starved. The curious thing is they could have moved one cell row to the left and been on honey. Does anyone have an explanation for this or is this just one of those things. I checked them last Saturday and they were active and I noticed they had adequate stores and today they were dead. Any thoughts would be appreciated.
