I have a small colony that I'm worried about going into winter. The queen is good, she didn't have enough bees to make places for her to lay. Realizing her plight, I equalized yesterday but don't think the colony will be prepared for winter. So, what if I stack her colony on top of a strong colony with a excluder separating them so the top group will benefit from warmth rising from the lower group?

Has anyone tried this?
