As of today, I’m beginning to reconsider how I do my first hive inspection of the year. I like to reverse the hive (i.e., move the brood nest to the bottom), but next year if I find all the bees are contained in a single deep (which is often the case), instead of moving the bees to the bottom and putting another deep on top, I might move the bees to the bottom and leave the hive like that — as a single-deep hive. It shouldn’t be a problem as long as the bees have enough honey and the queen has some room to lay.
Bees that are confined to a smaller space supposedly work that space faster and better than they would if there was more space (e.g., if there was a full deep on top of them). Apparently, this is common knowledge for beekeepers who always have nucs on hand. The colonies in their nucs tend to build up quicker than those housed in full-sized deeps and hives.
I say it’s common knowledge, but it’s not something I’ve had any experience with until today, sort of, possibly. A brood nest of a colony that I reduced to a single deep a few weeks ago (instead of reversing it) is expanding at least twice as fast as the brood nest in my other colonies that were reversed. It could just mean I have a better queen in the single-deep colony. Or! Maybe the bees in that single-deep hive did better because they were able to concentrate on the limited space they had instead of spreading out their efforts across twice as much space.
I don’t know. But next year when I do my first hive inspection of the year, instead of reversing the hive, if the bees are in a single deep, I’ll reduce the hive to that single deep until the brood nest is ready to expand into a second deep.
March 2019 Postscript: This is pretty much what I do all the time now. If the bees are contained in a single deep during the first hive inspection of the year (sometime in April if I’m lucky) and I don’t see bees on all 10 frames yet, I’ll toss the second (or even third) deep and let the bees expand into that single deep before I add a second deep.
I’ve overheard many conversations about this, not with local beekeepers but online where I continue to tap into the knowledge and experience of some of the world’s best beekeepers. Some of the phrases overheard in these conversations include, “You don’t want to demoralize the bees by giving them too much to work on,” or “Small colonies do better is small hives and big colonies do better in big hives.”
Like I said, that’s pretty much how I play it these days. A colony with only 3 or 4 frames of bees seems to build up faster when it only has 6 or 7 extra frames to work on instead of 16 or 17 frames. It seems to make sense when I stop and think about it.
A single deep is an easier space for the bees to keep warm – probably important in your climate.
I know a beekeeper in Prince Edward Island (not too far from Newfoundland) who keeps her bees in single deeps all year round, gets plenty of honey from them, etc. That always seemed like crazy talk to me — and it still does seem crazy for wintering the bees (mine usually need a full deep of honey to stay alive) — but I can easily see how it would work in the spring as the colonies are building up. I’m tempted to try a single-deep hive all summer too, but for now I’ll stick with what I know. I can’t afford to lose another hive.
