Many people are concerned about things like balling, if the queen is not accepted right away, etc.
I have stated in the past, especially with balling, that if the bees wanted a queen dead, they would kill her very rapidly. And if you see balling, close up the hive and wait a few days. Chances are the queen will do fine. Do not attempt to catch her, recage her, or anything else. (This of course assume you did your job and reasons like a second queen in the hive was not true.)
I once had a hive that had swarms cells opening up as I lifted the frames. I caught about 8 virgin queens. I lifted one of the frames, and there were two queens walking towards each other. I thought to myself, this will be interesting. I never seen two queen go at it. So there they are, walking towards each other, and almost as if you would pass someone walking on the street, and catch a glimpse of a familiar face and do a double take, that is what the queens did. They kind of were passing each other, and you could see a split second hesitation....then they went at it.
And boy what a disappointment! The fight last no more than two seconds. The one queen was all over the other and as soon as the other queen was stung, they quickly separated. The one queen walked away. The other started twitching, and the end came swiftly.
What a waste. If I knew that was going to happen, I would caught one of the queens.
Seems queens, perhaps unlike two workers going at it and struggling for what seems a minute of more, has little defense strategies. They are large and present little defense. They can be killed within seconds.
Remember that the next time you see bees balling a queen. If they wanted her dead...they would kill her just as fast.
Just a rambling on a cold day..... :-D
