She is def. part barred rock because the only roo was a barred rock. My coworker that I got her from has 13 other breeds and didn't know all the types. I hatched her out last summer.
If the rooster was a barred Rock, my thought is the momma was a silver laced Wyandotte. That's a classic Wyandotte body shape, and the rose comb is dominant.
I had a rooster of basically the same cross, but I didn't keep him long enough for him to really mature and get the nice heavy body, he was still gangly when I had him....
