First off, thanks to everyone on the forum for posting and helping me out with my amateurish questions. I really appreciate it. This place is a great source of info!

Last Friday I went up to the farm location(on the side of a mountain here in the tropics) where I keep 4 of my 5 hives and I was greeted with the sight of multiple Asian hornets actively killing off my bees. I had problems with hornets before, but not to this level. Usually, I would kill some when I checked on my bees, but this time, I probably killed at least 10, and they just kept coming. It was frustrating to watch them fly around and grab my bees and then fly off with them.

Anyway, I knew that i needed to move these hives away from this location ASAP. I waited until nightfall and moved them down off the mountain to my house, which is about 1 hour away. They are now on my roof, where there is no danger of hornets(at least not until now) and I where I can keep a close eye on them and hopefully nurse them back to health.

I have 5 hives, technically nucs, though they are in Langstroth boxes. They don't sell nucs in nuc boxes here. They just remove some frames and sell it that way.

I am having a major issue right now as it seems these hornets significantly reduced the population and weakened the hives. I now have multiple hives that appear to be queenless. I checked all five and found almost no brood or eggs. In one hive I found maybe 10 cells of capped brood and that was it. Most did not even have stored honey. I also accidentally killed the queen from the weakest hive, so that hive is now completely dead. I think it was beyond saving anyway.

So 2 of the remaining 4 hives have empty supersedure cells and i heard a piping queen, so I am hoping they have virgin queens, but I am not sure, though I definitely know I heard the piping.

So, what do I do about the weak hives with no sign of a queen? Do I combine them with the stronger hives?

I have been feeding them sugar so they get strong, but even the strongest hive (that was never on the mountain with the hornets) has stopped eating the sugar. Does that mean the nectar flow is on?
