I know what a silkie grey isMy Orps thank you!
If you have a correct Partridge hen or pullet, and you can see true partridge markings over the wings, most judges will use them if they have superior type.You can't just call a bird with a black crest, red,or wheaten chest, tan and grey back, etc,. a partridge.All those feathers, smoothed down, should show a partridge pattern, just like a gray should be a chinchilla grey, not another breed's grey. So many people don't read far enough in the ABA standard about grey, and miss the Silkie Grey. I bought 8 very good chinchilla grey silkies on traders' row one time from a very experienced breeder who had never finished reading the color on Grey in Silkies. He kept the incorrect ones described earlier in the standard!

Here is that picture I found.

I'd love to have some greys!
