A while ago I bought two Australorp pullets from Runnings. From the start one looked different than the pictures I had seen, and it still look different today at about 8 weeks. It's had much different facial markings. Here are the pictures I have which are somewhat limited especially from when they were young: This was the typical looking one above. This was the different one. It had a white belly and bottom with a little white on the wings. The two front chickens who are mostly black are the australorps at 8 weeks. On the left is the different one- now it has black eyes, beak, and everything else except for a little white that can be seen at the tip as it unfolds its wings. The other still has white facial markings. I also find that the fully black one is a little more aggressive and surprisingly friendly. It doesn't seem to get spooked at all. Does anyone know if it is a different breed, sex, or is just different for some reason?
