During an inspection I came across some strange looking bees that had absolutely no hair on them. At first I pegged them as old bees that had their fuzz worn off, but upon closer inspection they are completely bald and shiny. They don't appear to be sick or deformed. They can move around and fly like normal fuzzy bees. Genetic defect maybe? This hive started strong but has been struggling as of late. When I inspected I found no brood, no queen and almost all the available combs were filled with honey. I donated a couple frames of brood from another hive. One frame of mostly capped brood, one frame with uncapped larvae, eggs and an empty queen cell (in case they need some help). About an hour or so I came back to do a visual check. It appeared the bald bees were being dragged out flown off. Maybe they were old robbers? I put a robber screen on, just in case. In the evening I took off the robber screen to clean a pile (20+) of dead hairless bees blocking the entrance. This hive is plugged with honey, it doesn't appear they are being robbed. Any ideas? Maybe these bees are related to why the queen is missing? If it helps, I can post some pictures of these odd bees this evening.
