Norfolk Grey

Norfolk Grey is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Norfolk Grey rather than just read about it. In short: The Norfolk Grey is a British utility breed of chicken that originated near the city of Norwich, in Norfolk, England, in around 1910. The breed was originally created by Frederick W Myhill of Hethel, Wymondham under the name Black Maria.

Key takeaways

  • Norfolk Grey belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Norfolk Grey to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Norfolk Grey from memory before moving on to harder problems.

Reference excerpt

The Norfolk Grey is a British utility breed of chicken that originated near the city of Norwich, in Norfolk, England, in around 1910. The breed was originally created by Frederick W Myhill of Hethel, Wymondham under the name Black Maria. It is a rare breed which is currently considered to be at risk by the Rare Breeds Survival Trust.

History The breed was originally created by Myhill before 1914, possibly as early as 1908. During the First World War, the breed was allowed to free range while Myhill had departed for military service. On return, Myhill discovered that the birds had cross bred with other breeds and the strain had to be recreated. The Norfolk Grey was first exhibited under the name Black Maria at the Dairy Show in 1920. In 1925, Myhill applied to the Poultry Club of Great Britain in 1925 to have the name changed to Norfolk Grey as the breed did not gain popularity under Black Maria. The Norfolk Grey came close to dying out in the early 1970s but a private flock containing 4 birds was found in 1974 and the breed was revived.

Characteristics

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. Cocks usually weigh some 3.2 to 3.6 kg (7 to 8 lb), and hens 2.25 to 2.7 kg (5 to 6 lb).

Utility aspects

The Norfolk Grey was bred to be a utility bird, both for production of eggs and for the table.

Eggs Approximately 150-220 tinted (pale brown), medium-sized eggs per year from a healthy hen, and the breed can be expected to continue laying well throughout winter.

Meat Cockerels make good table birds if allowed to mature slowly. The meat is more gamey than most other common breeds.

Worked examples

Example 1 — a first encounter with Norfolk Grey

Start with the simplest possible case. Write down what Norfolk Grey claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Norfolk Grey before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Norfolk Grey ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Norfolk Grey

In research
Norfolk Grey appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Norfolk Grey in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Norfolk Grey is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal breeds on the RBST Watchlist, Chicken breeds, Chicken breeds originating in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life
Look for Norfolk Grey outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
