I did a bit of hunting for you and she's possibly a red shouldered Yokohama. I'd never seen her colouring other than on a jubilee Cornish and she's far too fine to be one of those!
I agree the first bird is a white laced red Cornish. She's a juvenile, so she's not as broad. But I'm thinking a frontal pic would show the classic Cornish shape, with the broad stance and wide breast.
She's definitely got the lacing. Red shouldered birds aren't laced.
