Casey,
        There is a book entitled "Bumblebees" by Oliver Prys-Jones and
Sarah Corbet. It includes sections on bumble bee nesting behaviour and
the establishment of captive colonies. It also contains a good key to the
bumble bees and discusses interactions between bumble bees and natural
enemies which is very
useful if you plan to relocate your colonies outdoors. I believe it was
published in 1987 by Cambridge University Press.
 
                                                Sincerely,
