Gotta agree with Bill and Alan.  I have a lovely colony that had their tree
downed by lightning one evening in June.  A big powerful colony, several
gallons of bees, but we were able to scoop them into the hive by the quart
with bare hands, and they remain just as nice today.  Breeding is, of
course, unknown.  The queen is pumpkin colored, but her bees are every color
from jet black to blond.  My mentor has hived many feral colonies, and most
have been gentle.  One of these had combs 12 feet tall and had been
established for 50 years, but were gentle.  In fairness, we still may owe
such gentleness to good breeders, as some folks who don't take care of
perfectly nice bees let many swarms issue.
