How odd. I think Polish can be ruled out. There would be at least some crest showing. That leaves Ameraucana and Faverolles, both of which have beards. And this bird does not have a beard. It doesn't have the pea comb of Ameraucanas nor the fifth toe and feathered legs of Faverolles. My guess is that perhaps a rambling rooster made a stealth visit to one of the Faverolles or Ameraucana hens. Or else a rambling hen paid a visit and took off after leaving an egg. Or the breeder brought in a chick or egg from elsewhere and forgot. Because the only feature of the three breeds listed is white legs, like Faverolles. Otherwise, nothing. Were the Ameraucanas pure or just Easter eggers?
