My roo in the pic (he's a mix, not a true Ameracauna-I believe silkie since his legs are lightly feathered and he came from a light pale brown egg) he was an ordinary yellow chick, just had puffier cheeks..lolOh! I have 4 Americana and only 1 has the puffy cheeks ;-) the rest do not and they looked exactly like the lil striped guys you have
