They're young and can still do some changing, but they do look similar to my Barred Rock Cockerel. Barred Rock pullets don't have so much white barring. Of course they're barred but the white isn't so thick. It's in the genetics. Can you post a picture of each one? I see the one that is pictured individually, but the other isn't in the best position for the ones that are so good at this to tell. Also, my BR pullets had dark legs (on the front of their legs) but I've heard this doesn't always apply with Hatchery BR's (mine are Hatchery stock).
Please keep in mind that they're young so it's not always obvious at this age. They still have growing and feathering to do yet. I am only basing my thoughts on the 3 barred rocks I have, and that's not very many, so please keep that in mind. I'm pretty new
