During winter us beekeepers start to miss spending time with our bees. We just want to check in on them and make sure everything is perfect but we also don't want to disturb the cluster.
I've found an observation hive to be a great way to continue observing the behavior of a colony. I typically choose a small colony in fall that to no fault of their own won't survive winter outside. Usually a late rescue that didn't have time to build stores.
Above is a modular 2 frame setup that is expandable through stacking more boxes. I decided to go with 2 frames vice the 1 so the bees could find dark space anytime they choose.
If you'd like to know more or have questions let me know I'd be glad to answer questions!
