Norfolk Grey is considered to be a heavy breed but does not grow as large as many other heavy breeds.
The development of this breed is not factually known but it is thought that Birchen English Game and possibly Duckwing Leghorns were used in the makeup.
The game inclusion would account for the excellent meating ability and the Leghorn for the laying ability.

They have a single comb and a red face with black eyes while the legs are slate or black.
Plumage is attractively marked and the male has a beautiful silver hackle striped with black as is the neck, back, saddle and wing feathers, while the rest of the plumage is black.
The hen's hackle is similar to the cockerels but she has an otherwise rich black feathering all over apart from the throat which is silver laced.

They can produce a good-sized carcass for meat production if they are allowed to mature slowly and are regulars at shows where they win prizes.

The Norfolk Grey is an excellent forager and does well when free ranging.
Males reach 3.2 to 3.6 kg (7.1 to 7.9 lb) while the female reach 2.25 to 2.7 kg (5.0 to 6.0 lb).
