Six-pound swarm hived today. Long story, friend’s best intentions to prevent a swarm by preemptive split of the hive that looked to be preparing to swarm, except for one slight detail: One of the splits never moved away from original position. All foragers returned to original position, half the space previously available. As can be seen, swarm ensued next day, early afternoon. Luckily it was so heavy they landed on a relatively low branch, and could be safely gathered, and hived. Fun project!
