In Wisconsin, I would put the empty wet "under" the hive.Single brood box works for me but upon honey harvest there are a ton of bees that need a home. At harvest time I would like to add a wet deep to the colonies for extra space for the overflow of bees but also to store extra honey for our wicked winters. But these 2nd boxes would need to come off in early spring before they start brooding into both.
The question is should the wet be put on the top or on the bottom of the brood box to increase the likelihood that they will be in the top box by spring?
The goal being to quickly go through in early spring and pull off all bottom boxes (assuming they will be in the top box by then)
I will be fattening them up for winter by fall feeding immediately after harvest. I use only deeps.
You have the stores properly set up and also have cluster space.
Sometimes the bees move up and in the other case the bees would be in an empty with stores under them.
I BTW do this quite often.
The slight difference, for me is, I put a medium wet into a deep and place it under the hive, for cluster space, and to raise the colony a bit above the entrance cold air. As well in spring there is no brood in the lower in the spring.
