This is painful to read, squarepeg. I am truly sorry for your troubles, and do hope that your current colonies serve as a stable basis for your rebuilding efforts.that makes a 100% loss of two yards having 12 hives each starting last year about this time and ending last week. efb sucks.
unfortunately fusion_power's gifted hive caught efb from the one mentioned above and had to be burned as well. i'm truly sorry about that dar.
It is sobering to see how everyone (and almost everything) has been impacted by this pandemic. I do hope you are able to get your business successfully re-engaged.
