Question on ventilation holes drilled in deep boxes?
Reading thru some of my books, I have a couple of questions about the ventilation for winter. The latest book I am reading says its a good idea to drill cork sized holes in both deep brood boxes, right below the handles. How many of you do that?? I already have the mouse guards on and I want to make sure ventilation isn't a problem.
Should I do this in combination with the Popsicle sticks under the inner cover?? How much time do I have before I need to do this? Temps are crazy here. They are real active today, and I noticed they are still bringing in pollen as well!
I am ready to hear 400 opinions :-)
