I have been trying to decide what kind of bottom board to use in Illinois. I know a lot of people use screened bottom boards while others use a solid. I was also going to use a quilt type box for my inner. With a screen bottom board and a quilt top, do you guys think that would be to much ventilation in the winter or summer. For my quilt box, I was thinking of just converting a 5 5/8 supper and also modify it be a top entrance. Any ideas on this?
