What breed and sex is my chicken

[Albertxy]

Hey there, first time chicken holder I need help finding out what breed and sex my chicken is

 

[nuthatched]

it looks like a bantam, how big is it?
maybe old English game mixed with something else?

Pullet/hen depending on age. Breed, I'd guess old english game bantam but I suck at bantam breeds.

I don't know how old she is I found her wondering the streets a few weeks back and no one claimed her
