The title sounds like a Queen Rearing forum question, but I think it probably goes better here. I'm building a 4-chamber hive body mating nuc and instead of drilling entrances into each side of the hive body, I was thinking about placing a 1.5" shim under the hive body and notching it out on each side. Is the extra space under the frames going to create a burr comb problem. Am I asking for trouble? I'd like to avoid putting holes in a hive body that I may re-use one day.
