Re: Queen bee "narcolepsy"?
It's happened to me Joseph, more than once. It's especially happened in hot weather. I don't use the plunger, I just grab the queen by wings with right hand, place her on comb, then gently hold thorax with left hand to free the right, and then mark her with one of those water based pens. On a few occasions, in hot weather as I remember, in strong hives, the queens would, like, feint or something. It scared me but what could I do? I put them in the hives and like you, the next day they were fine. These were queens I was marking for someone else so I was quite worried, but they came out fine but I never heard any more so don't know longevity of the queens.
20+ years, raise my own queens, feed when needed. I treat, but have not perfected varroa management yet.
