I use two deeps most times. Most of my colonies are large enough to fill one deep with just the bees.
I try to go into winter with the second full of stores, on top.
I will rotate on my first or second inspection, if the queen and brood is on top. At this time I can clean the bottom board and/ or replace it if needed.
This is part of swarm prevention. If I have to I will rotate again around the 1st to 15th of april.
I may split at this time, or add a third deep, depending the population build up.
For those in the north, "don't" think about wintering with one deep, unless you have two or three mediums of stores.
For those in the south, don't forget, with mild winters the bees take a lot of stores because they fly a lot when 50 degrees and above.
From the first of Feb, till the First of April, it is easy to loose a colony to starvation in the South.
Been there, done that.
It is best not to use someone elses Practices. In starting out. Experment and do what you and your bees do best with.
Best advice I can give.
