I have half Silkie / "Americana" cross (not certain that is an Ameraucana, as I didn't create the combo myself). Can't wait to see her little eggs.
The Silkie-half came out as a smooth Silkie, she is 'banty' sized (though still only 10 weeks or so), she has five toes, with ear tufts and a beard, so cute and a wonderful little personality. She's a top favorite of mine
What color is the Silkie half in yours? Seeing as black is dominant, I assume mother Silkie in my combo is black. My little pullet has a lovely green/blue/purple iridescent sheen. And did I mention that cute, smart and lovey personality? hehe.
