I could throw a rock and hit I-80; near Iowa City.
This year I'm running 2 deeps, 10 frame. I bought 5 frame nucs this year, Carnolians, and had 100% drawn comb to give them. I also gave them each about 5 frames of honey from last year, fed between apple bloom and when white clover started. So they got off to a good start. Obviously I took some deep frames away from them in July when I did splits.
I'm not sure what the hives are weighing now, but when I took honey off the deeps were light. I left each hive with 2 deeps and 1 super...I would like to go into winter with that all filled. They are 100% drawn comb, but on average I left them with 5 frames of uncapped honey/nectar and 5 empty frames in the supers. Of course the late splits are not that far along, but at this point they have the first deep filled, I gave them a super half-filled with honey from the other hives, and plan on adding a second super ASAP. They are building up fast...like I said, they sucked down 2 gallons of 2:1 syrup in a week.
Why did I lose hives last year?
They had plenty of honey. I treated the hives 3x with oxalic acid vaporized, in August. I really think it was the weather. We had a week of nearly 50F weather, and the next day it went to 0F with high winds for 3 days. I don't think they had enough time to cluster when the temperature dropped. The majority of people in my beekeeping club lost 100% of their hives, so I wasn't the only one.
Good question, I appreciate you wanting details.
