Re: Preserving the integrity of the brood nest
Haven't read the book so can only comment on the quoted portion in the opening post. I suspect much of this may be further qualified in the book and context for these remarks may be missing in the post.
There are 2 aspects to what he says. The first is that inexperienced beekeepers can and do cause havoc in a hive by spreading brood inappropriately, doing more harm than good.
But the second thing is that as a beekeeper grows in his or her understanding of the bees he should not be constrained by some kind of rule saying he cannot move combs, shift boxes or whatever. If he can see a need, or an advantage, and has the understanding to successfully make some manipulation which will benefit the bees, he should do it.
Me, I breed and sell bees. The more bees I can make and sell, the more money I have. I manage my hives intensively. The way I see it, they are working for me, and doing what I want, that's my view. Course the only way I can achieve that is work with them, and set things up so that they are actually doing what they want, to their greatest ability. If I just let nature take it's course, and never messed with a brood nest, I would be a poor man indeed, or likely doing some other job to survive.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
