I was gifted a bunch of chicks. 2 I know for sure are pullets (their pictures not included). These guys...well, I am pretty sure they are all roos- but one or two keep throwing me fore a loop. Can you please confirm for me?? I have never raised barred rocks or any mixed like this before..... not sure how much this breed differs from others... the one with the reallllly red comb s Buddy... he is obvious to me. They are about 8 weeks old. Thanks!
