I recently hatched Marans from a breeder and I visited him and saw his birds. He had blue/ black and splash flocks. Good looking birds and pretty dang good looking eggs. I hatched blue black and splash chicks, no surprise there. One chick though looks odd, he appears to be blue barred. I don’t know chicken genetics well, but is this possible or did another breed accidentally get to this birds mother? His set up looked pretty good and he was very proud of his birds. I know he didn’t do it intentionally if something got mixed up.
