At four weeks she is just a little bigger than the two pure khaki campbell females of the same age. She currently looks like a khaki campbell with facial stripes, a lighter chin and neck and a darker tail. The people I got the eggs from only have silver apple yards and khaki campbell's which why I believe that she is a cross between the two. Since she seems to have the brown dilution gene which is sex-linked, her dad should be the khaki and her mom the apple yard. So I am expecting her to be a good layer. Time will tell.
I am now sure my cross is a male. I think he is beautiful. He looks like a khaki Campbell with facial stripes, blue on his wings, and white under his wings. At 8 weeks he is as big, or a touch larger than my adult khaki male. He seems calmer than the full khakis and a better bug catcher.
