I have two 8-9 week old chickens that are black with brown tinges on their breasts. They have black legs. I have a full grown black australorp hen. My little ones have the same looks as her, escept their combs are yellow and my full grown one's are red. They also have brown on their feathers on the front. My grown one doesn't. Are the little ones Australorps? -M.P.
