Echo looks to me like a Whiteface Cinnamon Female. Black eyes with brown feathers are Cinnamon. With red eyes Fallow. Cinnamon ranges widely in intensity of color from chocolate brown to pale tan. It IS hard to tell if Echo is tan or grey. You could be right about the platinium however. A Silver tends to have pale grey but the platinum has pale tan. If you could get a good pic with natural light on the back may be it would be clearer. Also the age is an issue. If Echo hasn't gone through a molt yet even if it was male it would look like a hen. If Echo is over 6 months I would say you have a hen. In the Whiteface the face would be pure white. Echo's appears to have the body color on the face as a female or an immature male. Also I notice in all the pics the feet are at a pretty wide stance. Hens tend to stand with their feet further apart than males. It's a pelvic bone thing.
