Thanks. In my opinion, she looks nothing like an OE, and especially not a bantam. American game cross, certainly a possibility. I've only seen photos, and the birds are not yet laying, so no idea of egg colour. Here is a photo of the male: any ideas on him?
Seeing the hens pics then the cockerel confirmed my first thought- cornish mixes. The type is almost like a hatchery stock cornish x leghorn mix or something since they are closer feathered. The girls almost look slightly mottled but the cockerel doesnt show it as much
