I read somewhere recently that said barred rocks could be sexed at an early age because of certain traits. Does anyone know the traits that distinguish a rooster from a hen? I have 4 barred rocks that are about 3 weeks old and they all look about the same except one. He/she is a little bigger and has alot more tail feathers that almost looks like crowning when he/she holds them up. He seems to be somewhat like a leader of the other chicks, but not really any difference. Also, I have a blue cochin the same age. Is there any traits for them to tell rooster from hen at early age? Thanks in advance.
