I thought I had 4 strong colonies survive the winter from my 5 hives when today I discovered that one of them must be queenless with laying workers. The hive was full of sloppily placed drone brood and cells had more than one egg/larva. Drones were already hatched (I am in central Southern Ontario-too early in the season for drones in abundance). Is dumping the bees and removing the hive my next step? How do I keep the brood from rotting in the frames before I can reuse the frames? Will all the bees be lost or will they join existing hives? Nights are still below freezing at times. Thanks
