deffo not pure americans sorry to say, the cocks 2 heavy and the hens dont looks game bred either, too short legs and overall body shape. its extremely difficult to get pure americans or good americans in the uk, as the american game breeders in america will give anyone looking to import birds (or eggs) the shit that they dont want, so they havent started with the best birds, then as there are very few americans, they have to put other non game blood like aracuana ( i think your cock has some by the look of his head) to boost the numbers and stop them being too inbred, just y opinion
