Hi all! I have 7 chickens, all about 11/12 weeks old. I have 2 Black Australorp, 2 BR, 1 golden laced polish, and - looking for verification here - 1 EE and 1 partridge rock. I am curious if any stand out as Roos. I am wondering about my BA and BR mostly. One of my BA is really - runty? for lack of a better term. Its hard to compare her and the other for sexing, as she is really small compared to the other chickens and I believe BA to be a large breed. So could you all please take a look? I'd really appreciate it! Also if anyone could say if they think my breed guesses on the partridge and the EE are correct I'd be grateful!
