Our instructor, Bruce, operates the Homestead Demonstration farm as well as providing for his own family on his place.  He is a very knowledgeable man and imparted much wisdom to us over the three days we were there.  He called these ducks the Local Roving Gang.  They were loud and bossy and seem to think they owned the place.  I thought they were adorable!  Swaggering around like small bully boys quacking at everyone.
