Been keeping bees for a long time, so I should have known better. This is my second year making nucs to overwinter. Last year worked great, so this year I had a really good nuc going, in between two strong hives. They had been this way for a month with no issues whatsoever. A few days ago I went by a fed the nuc using a frame feeder, spilling just a few drops mind you, no major spills. Yesterday I went to the yard, opened the nuc, and it looked like the aftermath of a major battle. Every frame was completely empty with an inch deep of chewed cappings on the hive bottom. There were about 30 bees left in the nuc and no sign of the queen. I will never do that again! Let my experience be a lesson, be careful feeding a weak hive during a dearth, especially in the vicinity of strong hives.
