Dang. We're in a warm spell. The ladies were flying yesterday, so I decided to put on a hivetop feeder with some older honey. Warmed it up by setting the gallon jug in a pan of hot water, poured it in the feeder and set it on the hive. This was about 3:00 pm yesterday. This morning at 9:30 the front of the hive was splattered with large brown spots, as was the top and the the ground in front of the hive. Lots of dead bees outside, but some of them are from regular housecleaning that started yesterday. I pulled the feeder off, hoping I didn't destroy a colony.
