I'm totally new to chickens and I just got 6 roughly 5 month birds from a friend. They are all mixed breed and I have read every article under the sun and I can't figure it out (the ppl we got them from had no idea). The 1 below I'm leaning boy, but I don't know! I'm pretty sure based on the info I have it is a Barred Rock/Orpinton MIx
