I originally thought they were wyandottes, but as indicated by the comment below, that does not fit. I'm not entirely which breed they in fact are and I think they might not be pure-bred anyway. I do believe they have some wyandotte in them.
@Andrew Swales You are right and I guess I overlook that part. I really should have known as I in fact have wyandottes - the bantam version - myself. However I do think that in terms of color and body shape they have some wyandotte in them. But I don't think they are truly pure bred.
