As i just killed my 4th queen this year, perhaps its time to ask for advice. I was putting this one in a jzbz cage. Had marshmallow in the tube. had rubber gloves on for dexterity. picked her up by the wings like i am supposed to. put her head in the cage and she started walking in so let go of her wings and she walked in. closed the hole making sure she was not anywhere near it. put the cage down to close the hive. less then ten minutes later picked up cage and she's dead. are they allergic to marshmallow? did she suffocate herself in it? Here is a picture of the carcass. Previous deaths i was clearly at fault but this one seemed flawless. heart attack?
