I ended up with two hives this winter and spring from the nuke I bought the year before. I started feeding last fall and then also early spring. One of my hives swarmed. I caught the swarm, put it into a nuke box and then let the original hive requeen itself naturally. After that I was worried about my other hive that had not swarmed so I dug into it and made some splits with queen cells I found. Now I have 5 hives and they seem to be all going ok. I have extracted 5 gallons of honey and some honey comb. I'm happy with that. Yay :)
I suspect I started feeding too early in the spring which may have caused the swarming. The bee learning curve is quite a challenge.
