Looks like a pullet to me.
There are two of my Australorp girls in the background of this picture. One has a very upright posture, but she is all pullet. She lays eggs for me just about every day.
Great pics! Looks like my BA at that age. A pullet for sure. Don't feel bad about the standoffish-ness. They get friendlier when it's closer to time to lay!
Thanks Chicken Strut... oh they love me and usually are all over me literally, but I brought in the mean ole looking camera and I wasn't their normal looking chicken mom anymore bwahahaha
