I'm planning to create some nucs in July or August. I have never tried to overwinter a nuc, and I'm not sure what to do. I don't see how a nuc can survive in a northern climate like Indiana's, but I want to try it. This is my plan so far, but its subject to change based on other people's experince.
1. Make or buy some nuc boxes
2. Pick my worst producers in June, and split them into nucs.
3. Give each nuc a Carnie queen cell.
4. When each nuc has a mated, laying queen, give them a second nuc box on top of the first one in order to let them store honey from the fall flow.
5. In Sept, feed all nucs enough to let them store enough feed if needed without them having to use the stores they already have. I don't want them to backfill every frame because I've heard that it leaves them with no place to cluster.
6. Throughout the winter, feed on warm days through a hole in the top cover with a jar feeder on top.
The first goal is to go into fall with bees filling both nuc boxes. The second goal is to get them through winter. Then have them strong enough to be a full production hive in the spring.
Each nuc will be overwintered up against each other at a minimum of 4 nucs. I've heard that each nuc box should have a entrance at the bottom, and a vent hole near the top. They will only be overwintered in places that will provide a wind break.
I need any input I can get from those who have been successful at overwintering nucs in a northern climate.
