Silver-Grey
A variant of Dorking (Gallus gallus domesticus)

The best-known Dorking colour: silvery-white hackle and back on the cock with a black breast, and grey, salmon-breasted hens — all on the breed's five-toed, short-legged frame.
Keeper tips for this variant
The five-toed feet and short legs collect mud — keep them on dry ground and trim the extra toenail, which doesn't wear naturally and can curl.
