That’s a great idea. Hopefully, while adopting the most recent understanding that the overwinter huddling behavior is due to the insufficient design of artificial hives, not typical behavior. They should be cozy, too.
Temperatures here rarely go below 0°C, and when it does it’s often just for the night, so huddling isn’t a concern. What could be a concern would be summer overheating, but they actually put some thought on where to install those bee houses, they’re mostly shadowed by trees.
