Anyone good at Silkie chick colors? Got a mixed color group of silkies/frizzles and some have unique colors. One of the darker two (kinda grey/brown one) has some barring going on, but none of the parents were partridge unless they were hiding it. Parent colors (porcelain, silver/light blue, black, paint) I have got BBS colors down, but at a loss on these. Any thoughts on future color on these guys? Any input appreciated. Thanks!
