Female Salmon Faverolles. Like Marans the s is always there. 
I'd quarantine her away from your flock at a minimum of two weeks if you can. I'd preemptively treat her for lice/mites and deworm her. Faverolles are generally very passive birds. So watch her with your current flock when she is integrated, as they may pick on her. in fact, it might be easier to put one of them in with her every week until they are all together and she gets the benefit of being the first bird in the new pen.
