Trying to think like a bee colony now
being human, it ain't easy, but after so many millions of years I do believe they know best (better than me anyway) and will seek out a hollowed out tree if given the choice, so for my own bees that's good enough incentive NOT to put anything on the "inside" that bees wouldn't have put there themselves, but that's just me.
I had dinner with Michael Palmer last night before he gave a talk at a local bee club. I got a new saying from him, and I immediately thought of you.
"Bees make better beekeepers than beekeepers make bees"
