My 9 barred Rock hens are 4 weeks old and a couple of them having me scratching my head. Their combs are big compared to others and they are BRIGHT red, feet are huge and have WAY more adult feathers and are much bigger. Also today, it looked as though one, that was chilling out on my foot, was trying to crow. That or she was gagging on something. Here are a couple of pix of my questionable ones. Could they be roo's?
