That is odd! I haven’t seen that one yet. My guess would be the original queen did not fly out into the swarm of bees as they took off for some reason. If she’s half dead, maybe she can’t fly? Without a queen, I suppose there’s a good change the swarm of bees will return to the original hive.
What is your plan now? Are you going to leave your half dead queen in there and let them try again?
