I was working on building our deck today the chickens were out free ranging. I have 3 black Austrolps that are around 3-4 months old. I kept hearing the screeching terrible crow of a new comer. By the time I would make it around to see who was crowing they would all stop and I couldnt tell which one did it. Apparently this didn't go unnoticed by my big Rooster that is king of the yard, he came running when he heard it too.
