I HAVE 6 WEEK old baby hens and rooster. HOW CAN i tell the difference. I HAVE A leg horn that looks like a rooster above and below the beek, so I THINK IT IS A ROOSTER, but myfull grown hens also have the same red below and above the beek, so I AM CONFUISED, alSO, MY BARRED ROCK ONLY HAS A LITTLE ON TOP IS THAT ONE.
