If you’re suggesting stronger colonies would cope better and “it may have worked” you could be correct. But the simple question is why!!A dear friend Lorain Stevens was advised by the powers that be to shook swarm.that was early spring,l think l remember twelve colonies,young brood destroyed,it was a disaster.end of May strong colonies last year it might have worked.l just offer this for new beekeepers.
There is nothing a shook swarm achieves that can not be easily and more systematically accomplished with other procedures.
