I know that the cream colored chicks are Ameraucanas, but I don't know what the black ones are. They have feathers on their legs and feet, if that helps? Also, what are the brown ones -- two of the brown ones are the same shade, and one is a darker brown? Overall, there are three cream (Ameraucana), three brown ones (??), and the rest are the black ones. I ordered the Ameraucanas, and then an "egg production pack", so I really have no idea. Thanks so much for your help!!
