I know the father is from the very first rooster I posted - I don't know anything about him, since he's the one we purchased from different people, but he could be part Barred Rock. Not sure about the girl since it was a while ago, but her mother was Rhode Island Red x Barnevelder/Rhode Island Red (we have one pure Rhode Island Red and two crosses). I think her dad was another Barnevelder. Not sure how that could create how she looks, so I might be wrong. Her pattern does look like that of a partridge - she might have that in her.
Sorry for the lengthy posts, I'm pretty knew to all of this - I've never really bothered with the breeds of my chickens, lol. Thanks for helping me!
