I finally found a queen in one of my hives. Woo hoo!! Four years and the first One, unless you count once spotting a marked queen. She was fat and long and looked great. On the second to top box for some reason. I saw her on the bottom corner of a frame and she was heading for the other side in a hurry. She disappeared for a minute and showed up crawling on my glove! I wanted nothing to do with her crawling around outside the hive so gently rested my glove against a frame and off she went, down into the hive. Nice to finally see one for sure.
