We are new to backyard chickens, so I'd love the input of more experienced chicken people! We noticed some pink in the comb of one of our 4-week old chicks. Is it true that this signifies that she is likely a he? We don't see any wattles yet, but the pink in the comb is making us nervous that it's a rooster. And if anyone has any idea of the breed, I'd love to figure that out too.
