Rodney,
I agree with Bob Harrison that every day the queens are out of a
functioning colony is bad, however, I have kept queens successfully for
three weeks, and friends have kept them for five weeks by banking them in
the top of a queenright colony. I suspect they might supercede quickly,
but they do seem to function for a time. There are a number of articles
in the BEE-L archives. Do a search on "BANKING" or "QUEEN BANKING."
