About three weeks ago I took a frame of brood with the queen and put it in my indoor observation hive. The remaining frames I put on an existing hive, and used the newspaper method to combine them.
We had a few cold nights since then, and I decided to check on them today. I went through the top box, expecting to see little activity, and I found a few broken supercedure queen cells. I kept looking and I found a small queen in the upper box. The lower box also had a few broken queen cells, and two cells still intact. I wasn't able to find a single egg in either box, but I was able to find a handful of capped worker brood (no drone brood), but not much (I'm thinking it was left over brood from the former queen).
I was ecpecting to see the two colonies merge, but instead I"m thinking that the queenless hive attacked and killed the queen in the established hive, then started to raise their own queen. Problem is, there arn't any drone brood in the area (although there are a few feral hives). I know they didn't swarm, it's too early for that around here.
Do you think the small queen was a virgin queen? Where do you think I can go from here? Add a frame of eggs from a different hive and hope for the best? Or just sit back and watch what happens?
