I had an Araucana roo over EE hens. All chicks are rumpless and I've read that gene is dominant. So will all those chicks grow up and produce rumpless chicks no matter who they're bred to? I love my rumpless chicks and surprisingly they seem to be all pullets! Actually I forgot my Silkie was bred by him too and one silkie mix hatched and has a tail! Just wondering how many generations a dominate gene from only one parent will carry over?
