Ok, so I am a new B with chickens and I saw an add for a chick who is a cross of an Australorp roo and Americana hen. They say it looks just like a black australorp with a pea comb and came him from a green egg. SO...what will this chicken look like and if it is a girl what color of eggs would it lay??? If it is going to be something interesting...like oliveish I would love to get it but would these 2breeds make olive ethers???????
