Nock, what a story!!!! Two bees and a queen? ID has a good a guess as any. I might add a second possibility: a feral queen that settled in the only spot she could find that would accept her. Most hives will not accept a feral queen. If my guess is correct, she will thrive, if ID is correct, she should have effects of the poison soon.
Great story, one for the books titled:SUPER RARE BEE EVENTS!
