jaseemtp,........ WOW!!!!!
That is what I fear to run into one day. One criteria my mentor and his counterpart has for a hive is gentleness. Naturally, the bees that I've gotten from them are calm bees (well, one colony seems a little jittery, but...) and even the cutout from the dairy farm was very gentle. I figure one day, though, I'll meet some bees like those in your video. I'm glad you found the queen and de-throned her. Best wishes on calming those bees down and thanks for sharing the video!!
