I have two hives on my roof in DC, and i'm concerned about overheating when the temperatures are in the high 90s and humid. Both of my hives have screened bottom boards and sit on bricks, so there is a ventilation space under the hives. I'm a little concerned about leaving the telescoping covers propped up in case we have a wind storm, so yesterday I drilled 1 1-inch hole in each of the the two deep boxes of each hive. Has anyone ever tried this? Is it overkill? As luck would have it, we have rainy weather now 1 day after I made the holes, and now I'm concerns about chilling. Should I leave the holes open or should I cork them?
