I was reading Larry Connors' Queen Rearing Essentials.
"Natural healthy hives produce the best-fed queens during swarming and supersedure. Cell finishers (or builders) attempt to duplicate the high population and abundant food found during swarming, and create an area of reduced queen pheremone in a colony similar to what happens during supersedure." p.46
So is it possible to mess up a cell finisher and cause it to swarm because it seems to me that the finisher is really close to being a swarming hive. Why don't the bees swarm the moment the first cell is capped? I'm curious because if there is a way of messing it up I'd like to know what it is and avoid it.
