Seems to me it might be a good time (if there are several queens) to put them with just a few nurse bees in a nuc and see what grows. Nothing lost but a few nurse bees, and if they do well it seems like a free queen..?
If you are thinking in this direction you might find this link fascinating. www.mdasplitter.com/index.htm
I am going to try this out and see if I can gain some of my losses back. I don't know if I like the idea of just letting a hive less then a year old just fade. I will have to think that one out.
