Hi David,
I've got a few warres, some top bars, a hybrid top bar with a warre blanket and quilt that I was test-driving, a few tree hives (yes,
bees in
trees that we rescued after they'd been cut down), and
bees who live in the wall of our house who've been here for something like 60 years.
As far as winter, so far so good with everyone alive, though I have a concern about one of the hives, one we rescued in the winter that doesn't seem to be flourishing as much. But we haven't given up hope yet.
With so many hives scattered about the farm, we populate new hives from swarms that come from our hives, or wild bees that have moved into empty hives on their own (yes, it happens). ALL our hives since 2004 have been sourced from either swarms or cutouts from buildings.

This link is one of our bee trees with a 3-box warre on top of the 40" trunk that's contained inside some empty langstroth hive boxes (purpose: to hold the split tree trunk from falling open). Frankly, most of our hives don't look very normal. They all have a story to them. <g>
