That is what I was thinking, which is cool because I have one 2 year barred rock hen and I wanted a mate for her. which I got(Ithink) haven't looked at all the wings yet to see if male or female.
from what i have read and from the baby barred rocks i have hatched, the smaller the spot on the head and darker the feet its a girl, the bigger the spot and lighter the feet its a boy
so far with my babies ive been right, if you do a seach on her for sexing barred rocks there is a post about it, good luck
