One of my hives, it would seem (through all the research & questions I've asked) had found an insecticide tainted source about 2 weeks ago. I lost about 1000 bees, but for a week now the dieing ended, all seems well. Upon inspection today I noticed what looks to me like 4-5 queen cells that have hatched. There are about 7 out of 9 frames in the bottom box that have a fair amount of capped brood, there is some larvae and some (not a lot) of new eggs. I kept the second brood box on the entire time of the die-off, it was 4-5 days after I added this box that the die-off started. I kept it on so not to disturb the work they started, though it wasn't a lot, but before the die-off they bottom box was completely drawn. Now, nearly 3 weeks from when I put the second brood box they have virtually done nothing in it yet. Is this because they are "rebuiliding" from the bottom up again due to the die-off? If what I"m seeing is a re-queened hive is there something I should watching for to see if she's of quality? Could the re-queening be a result from the insecticide issue? In the early part of the die-off I put out some sugar water for them, seems like they're not taking it though, seems like whats gone could be a result of evaporation. Left on too long can it go bad?
