Yeah, this.
When their honey is "done," bees put a wax cap over it. In winter/early spring, you don't want to add any moisture to the hive, so you'd have to find some honey comb that is capped.
Would it work to set some frames aside (without extracting them) when you harvest the honey. Then give it back if the bees need it or extract it in the spring if they don't need it.
Or small amounts, narrow-necked containers, hole into the container of honey, or wax coat to minimize evaporation.
Unless you had a hive that had died, you'd be robbing one hive to feed another.
Sounds like a logical idea, though.
After the first year, you'd be "robbing" yourself. Quotations because I don't think harvesting is robbing them.
It might be expensive. Or it might be an investment into the health and well-being of the bees.
I think this might sound like criticism or arguing. I'm not trying to do anything like that - I'm just trying to give people something to think about.
And, I don't keep bees. I can't try it myself to see how practical it might be. I'd like to some day and made a little progress toward it - mostly working on the bee pastures and reading about what other people have tried.
I would probably start with the same methods as at least some other people like I've done with the chickens. I can't do everything I'd like to do (more free ranging, improving the range, have a rooster, let hens set and rear chicks, and so on.) But I'm having good success with some unusual (or at least, uncommon) methods.
