At the end of last year I allowed one of my colonies into a super full of honey as a wee treat. However, now that spring has arrived, how/when do I get the queen back down? I'm worried that if I go in to early, I'll freeze the colony, but if I leave it too late will I end up with a lot of brood in the super? By the way, the colony has survived the winter extremely well, and is doing great.
