I just did a set of grafts today to try and raise some queens from my best hive to requeen some dodgy ones. Anyway, I am trying a different starter/finisher system that a friend who is a queen producer uses. A very strong queen right hive - grafts and all open brood above an excluder and a super of honey. I think he got this from a Larry Connor class. I know that it produces very nice cells, but the queenright hive often tears them down at the 11th hour. My friend uses an incubator to avoid this issue - I don't have one though.
So I'm wondering why can they not be placed in mating nucs as soon as they are capped?
Gonna build me an incubator next year.
