I'm looking for the breed(s) of only the black chickens. In the pictures, I don't know if they're Australorps or not because their eyes are more of a yellow/haze color instead of a dark brown, which is what makes me wonder. They lay a cream-light brown large sized egg.
I have to agree and say hatchery Australorps. They get small combs as adults, have almost solid black eyes, high tails... They look just like my 2 australorp girls.
