I caged a queen and four workers, gave them to a friend and a day later they are all dead in the cage. If I miss handled one of them they would not all be dead. They didn't have an fondant but I didnt think that was necessary for a couple days. The only thing I can think of is maybe at some earlier point the cage came too close to the oxalic shop towels I was using? Its been a little cool but no temp extremes. Any ideas.
