Re: Should I feed a swarm?
While you guys are busy with the ruler, keep in mind the OP is in NC. My bees are taking syrup now and in large quantities on the warmer days and I am 100 + miles north of Dmlehman. In fact, I am pretty sure we have a fair amount of nectar and pollen coming in, so any feeding is supplemental for those days the bees can't fly. An inhive feeder or hive top feeder like the baggies will be fine.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
