Deerman, even most of the beeks in Canada now overwinter their hives.
Ohio has a very healthy number of beekeepers, of which virtually none practice cull-and-replace. With the current bee shortage, most have now come to understand the importance of not killing bees, and the ease of overwintering (especially in your area) if the proper steps are followed. There is a lot of info out there on winter setups, but your area should be a pretty easy one for overwintering hives in.
I have 3 hives, my Dads from years past. Have had them for a few years.
Talk to a Guy that had over a thousand and he replaced them every year??? Thats was over 3 years ago. He was in Northern Ohio.
Just wonder if thats was normal.
Know a little about bees, but alot more to learn. These were my Dads he kelp them here on my place. Didnt even remove any honey this year.
Did catch one swarm from them this year.
As for replacing that many hives each year, it's not the normal practice these days. To be honest I'm pretty sure that most would tell you that in this day and age, it'd be pretty severely frowned upon. You won't find folks on these internet forums that do it either.
I hear you on the lack of honey this year. This was a bad year for folks in many areas. Some folks here in our area didn't really get a crop either.
