So one of my hives has many, many (hundreds) of dead bees out in front of it. Still a Very active hive with a great amount of foragers coming and going. This evening I squatted and watched the entrance and in eight minutes saw them drag three end stage (pupal) drones out and discard them. These drones were within a few days or less from hatching. Am I seeing "super hygienic" behavior? I can open up tomorrow and pull frames but what will I be looking for? No obvious signs of nosema or anything else. I am really wanting to know here. Thanks, steve.
