Yesterday it stopped raining long enough for me to start treating
some of my colonies.  I noticed that two of the colonies have all
black bees.  Just last month they were Italian.  Could a feral colony
taken them over or have they superceded the old queen and the new one
mated with "wild" bees.  The brood pattern is excellent and these two
colonies are full of bees.
