I am a new beekeeper, just going into my 2nd year. A week ago, I split one of my hives. The hive had started making queen cells so I knew it was high time. I left them one (I thought) queen cell, almost ready to cap. Today I checked the hive. They seemed very docile but active. The queen cell had hatched, but I found two more queen cells, already capped. I assume these are an insurance policy in case the queen is lost before she is bred and starts laying eggs. What should I do. I am worried about after-swarms once the queen starts laying. I could create 2 nucs. Is this a good idea?
