Re: weighing hives
Laketrout it isn't rocket science but maybe 8 grade science. If you want an accurate weight you must weigh two opposing sides and add the results together. the reason is you have no idea where the weight is concentrated. It could be in the front the back or one side. I would assume it is never symmetrical and I suspect that the big difference you see from one hive to another is because it is not symmetrical. Take the time to weigh two opposing sides and then make the comparison.
