Ceasar, The thread said that he used Black Australorp with a white male, probably trying to get a larger size with the solid black. The Austrolorps do have white skin and red ear lobes but lay brown eggs. But they also are normally a good size, fairly short body type and medium tight feathers. I remember seeing some that had really nice green sheen and nice wide feathers along the way as well. I am sure that they were looking for other possible qualities also. Given the nice blue color of most Black AMs today, the brown egg genes must have not created much of a problem.
