Try *sliding* the next layer over the hive body instead of setting it down. Do it slowly, and the girls will have time to get out of the way. You'll probably still squish a few, but the biggest part of them with move.I can't seem to keep the bees off the edge of the hive body when I'm setting the feeder back on. I probably killed another 10-15 bees per hive just trying to put the feeder back on. Is this collateral damage or is there a better way?
