Today I pulled frame feeder and threw in a frame. After checking other hives while cleaning up .. I noticed a queen cell on the feeder. I opened the cell expecting to see larvae .. instead a bees hindend was wagging at me....soooo I removed her and marked the fully developed virgin and placed her in a queen's cage in a nuc. I'll follow up to see how things develop.. I couldn't just let her die....free-bee....I am NOT used to seeing queen cells attached on a frame feeder.....anyone else...?
