I know the gray one is a rooster I'm just not sure what breed. Can anyone guess what his comb is? The red/gray chicken. I'm leading toward rooster they are all 12 weeks the two pullets combs are yellow and pretty black one has no comb. The picture doesn't do her Justice. What do you think rooster or hen. Here's what I know they are barnyard mixes I picked up cheap. The two in question came from a chocolate Brown eggs. They are both 12 weeks but no aggression,fighting or chest bumping yet. But I do have a very dominant hen telling them what to do.
