Re: what % of colonies are productive?
If the definition of "productive" means did they produce some surplus then I would say 95% of our hives will produce at least some surplus. I feel the definition of good beekeeping in honey production is how high the percentage of hives is within a location that have roughly the same maximum production (on a good year that should be about 2/3rds) If one hive is far out producing the rest I assume there were some problems.
