There are many angles being promoted out there. I have had talks with some who wanted to discuss the differences in whether copper or steel wire would be best in a hive. Whether moving hives a few feet on top of a line of the earth's energy Field would be better. Whether metal tops on a telescoping cover interferes with the hives health. I find most of these ideas coming from some who take everything to the extreme so they can be different.
I like to use vegetarians as example. Why are most who they say are vegetarians, really vegetarians? If you really push the issue, most you come across, and if they are honest, a good number will acknowledge they do eat meat "occasionally". Very few are true vegetarians from the sense they do not just talk the talk, but walk the walk also. But what greater pleasure do they have, then when at a party and some asks "Have you tried the Swedish meatballs, they are fabulous!" And what happens next? The supposed vegetarian gets to comment about "Well no I have not. I'm a vegetarian". And for the next ten minutes, those within earshot are focused on the reasons why they are vegetarians. It's their ten minutes of fame.
I find the same for some beekeepers. They pick up on a few real far out ideas, and with little proof or studies to back up a single claim they make, turn it into talking points that are unique and it give them a chance to stand out from the crowd.
The only metal you should be concerned with are tinfoil hats that some seem to wear. Moving your hives onto earths energy lines, building triangles over top of your hives, or talking to the bees, all to me are for pure pleasure only.
I have some radical ideas and absolutely cringe from what the industry has done over the years. But there is a line of common sense I try not to cross over.
Since I am not commenting on anybody in particular, I hope my comments are OK to post.
