I marked a queen with a new Painters nontoxic pen today. Her hive is tiny and just starting to build. Four+ hours later we find her balled, four hive down, on the landing pad of one of the largest hives. We dug her out and put her in a roller cage. She is back in her hive for the night. Is there a difference between Painters pens and Posca? I had no known issues using Posca last year and wonder if it is the pen or a coincidence. I find it interesting that she passed two queenless hives to get to the one we found her on.
