Back of Hive #6 - a large gap between the brood box and top super.
Repair work complete - duct tape is like a wonder drug - you can use it for anything. The best part is when I open this hive again, it's easy to reuse the tape. I probably should get white now that they have duct tape in colors.
I may have mentioned this before but one of the best beekeepers I know uses duct tape on a regular basis. When I first saw his hives, I thought there's no way I'll ever put duct tape on my hives! Well, you know that saying - you should never say never.
