I like Blue Rocks. I can't seem to find them to buy; thought maybe breeding them would be easier. Also fun. My training is in animal genetics. I understand blue x blue = black, blue, & splash, and that black x splash = blue. Here is where the internet sources get hazy / nonexistant. (I think) Splash = black x white, and these splashes bred back to black sire make blue. Will this work with all White Rock hens and all Black Rock roosters? White Rock pullets / sexed chicks seem easy to come by. Black Rocks not so much. Any suggestions? Where do the Barred Rocks fit in? Could they be used instead of the Whites?
