I had something similar happen. The bees were thriving, filled top box with comb, and started a couple small combs on the 2nd box... then they swarmed! It was probably in late July or so when the swarm occurred. It seemed late.
Things have worked out though. The remaining bees raised a queen and they are carrying on. It was so late in the season that they never did make too much more comb in that 2nd box. 3 large lonely pieces that are not being used. The colony remained small after the swarm.
It’s now the end of October and my bee colony has thinned quite a bit more with the dearth and colder temperatures. I put an internal feeder inside the hive and put straw under and around the hive to insulate it.
I’m hoping they will survive the winter between feedings and their honey supply.
Does anyone have any thoughts? Has anyone else had a small colony filling just one box survive the winter? I’m also wondering if I should take out the bottom box that has the 3 pieces of comb in it.
This is my first year as a beekeeper. I realize now I should have done the fall feeding about 3 weeks earlier. Hoping for their winter success. 🤞🏼🏼
