Small hive turns out to have no obvious brood... oops. Well it may recover I suppose.
2nd hive has brood, and a fair amount of stores, but still seems reasonably liquid. So I don't think I need to hurry about extracting it. Might do it tomorrow, time and the tide suiting.
Phone John Rayner, CBKA, to see if they still want my 2nd hive, and they do, so he will probably come to collect tomorrow evening. Which will be a bit more free time for me!
