Hello all! I seem to have become braver as I have become wrinklier! I am now very keen to have a couple of hives!

I have happened upon a lot of info on top bar hives and am intrigued! My concern is that Scotland may be a bit chilly for this type of hive? I wondered whether building the sides out of 2 inch thick wood, and filling both ends with wood shavings in the winter would be of benefit in this respect?

Does anyone have experience of this type of hive in Scotland?
Thanks!
