Sumatra chicken

Sumatra chicken 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 Sumatra chicken rather than just read about it. In short: The Sumatra is a European and North American breed of chicken. It derives from birds imported in the nineteenth century from the island of Sumatra in Indonesia as fighting cocks.

Key takeaways

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

Reference excerpt

The Sumatra is a European and North American breed of chicken. It derives from birds imported in the nineteenth century from the island of Sumatra in Indonesia as fighting cocks.

History The Sumatra derives from birds brought in 1847 from the island of Sumatra in Indonesia to the United States for use as fighting cocks. It was recognised in the United States in 1883 and in the United Kingdom in 1906. Birds were imported to Germany from the United States in 1882.

Characteristics The original colour of the Sumatra was the black – often with a rich beetle-green sheen – which was added to the American Standard of Perfection in 1883, and was standardised in Britain in 1906. The blue is the only other colour recognised by the American Poultry Association; it was added in 2003. The Poultry Club of Great Britain recognises black, blue and white, while the Entente Européenne recognises the black, black-red and wild type but not the blue. Cocks weigh 2.25–2.70 kg, and hens about 1.80 kg. The comb is pea-shaped and as small as possible. The beak, face, earlobes, throat, comb, shanks and feet are as dark as possible, preferably black. The Sumatra retains a strong flying ability, unlike most modern chicken breeds.

Use The Sumatra may be reared as an ornamental breed or for showing. Hens are good layers of white or cream-coloured eggs, of which they may lay about 130 per year. They are very good sitters, and may be used to hatch eggs of other breeds, including water-fowl.

Worked examples

Example 1 — a first encounter with Sumatra chicken

Start with the simplest possible case. Write down what Sumatra chicken 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 Sumatra chicken 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 Sumatra chicken 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 Sumatra chicken

In research: Sumatra chicken 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 Sumatra chicken 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: Sumatra chicken is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chicken breeds, Chicken breeds originating in Indonesia, Chicken breeds originating in Sumatra, so understanding it makes those chapters shorter.
In everyday life: Look for Sumatra chicken 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.
