That's not "partridge" you're seeing, that's a cockerel carrying both gold and silver genes. Dark Brahmas technically ARE partridge, just a silver version.
They look okay but the adult male has some droopy wing carriage and too low of a tail angle. He looks a little more like a Rock than a Brahma in type.
