Just noticed the pea comb, so the brahma would have to have been the mother. Or maybe it's a rose comb, your white rooster is the father. Either way, 2 single combed chickens are not the parents.
Your white chicken sounds like a barred chicken with recessive white. When bred to another chicken, his chicks would get the barring without recessive white. Because of the feathered feet, you are probably right about the brahma being the mother.
I could also be completely wrong so hopefully...
