Sorry - I have not learned how to reply by snipping most of the previous
posting -->
I just wanted to add my twp cents worth:  Queens in cages, shipped in
quantity for requeening, are very interesting,in that thhheir individual
sou;nds are quite audible and not all exactly the same.  A little
imagination might make you think of a very special choir, as the multiple
tones are quite musical.  Incidentally such a package has its own quite
distinctive odor, too!
