I posted a little whole ago about my rooster being dropped off by someone abandoning him. He went on to father quite a few chick's. Here is a picture of one alongside a picture of him...obviously nothing a like...but Roo, the brown spotted one is my only rooster and so has to be the father. I believe the mother of the gray one is a Black Australorp (named Raven). Is there any breed of chickens that looks like this gray rooster that could be in either Roo or Raven's geneology?
