The second one is LF she came along with the others as Standard brown egg layers assortment from MPC.
This is what the Barred Rock looked like soon after we got her
This is the second chick, a side by side comparison to what she looked like when we first got her (mostly yellow with white feathers) to now (getting light red feathers)
Also I just noticed something kind of interesting. The pics you posted of the young barred rocks are white with black, ours has a yellow color where the white should be. Any Significance?
