Which one of these is my Black Australorp pullet and which one is my Black Jersey Giant? Both are 15 weeks old. I suspect #2 is the Jersey Giant just based on how slow she’s feathering out. She also still makes chick noises. The cockerel is a Black Australorp that is the same age.

JJ have yellow skin and Australorps have pinkish white. I couldn't pick out any yellow on any of those feet, though.
