Please help me understand what happened and what I can do. I brought my bees home yesterday and around 7pm I put the bees in the hive just like a demonstration I attended. I made simple syrup and added honey b healthy to the batch. I hung the queen cage off one of the frames in between 2 frames. Next I removed enough frames for the box to fit into the hive. I sprayed the bees with plain water and then opened the package and placed it in the hive. All of them seemed very active. Of course I used my smoker throughout the process as well. I placed the feeder and entrance reducer at the entrance and blocked the smallest opening with a tissue. The queen looked healthy and active as well. When I returned the hive was buzzing like normal. I didn't open it just listened. 24 hours after hiving them I opened it to remove the package and see if the queen was free. What I found was almost every bee dead including the queen. The bees that we trapped on the outside of the hive looked great today but the few bees inside the hive that had survived were very dark, almost black and could not fly. Am I cursed? Am I the worst or dumbest beekeeper ever? What do I do now with this hive? This is my first attempt at beekeeping and don't know what to do now.
