I live in North East Ohio, I have 2 deep boxes on all the hives, then I have the medium honey boxes on top of them. I leave the 2 deep boxes on the hives through the winter. The deep boxes are getting heavy to be handling, is it ok to keep the deep box on the bottom and instead of having the deep box on top of it making it into 2 medium boxes that stay on the hive through the winter? And if so, how do I change the top deep box into 2 medium boxes? Thanks for any advise on this.
