Pure Silver :
Unpure Silver :
As you can see on the pictures for the hens it makes NO difference for the Silver because sex-linked so hens have always only 1 doses and are pure "S/-"
Cocks must be with double doses "S/S" to be pure because when in single doses "S/s+" they have arancio shoulders = UNPURE coloration !!
