Hamburg chicken

Hamburg 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 Hamburg chicken rather than just read about it. In short: The Hamburg, Dutch: Hollands hoen, German: Hamburger, is a Dutch breed of chicken. The name may be spelled Hamburgh in the United Kingdom and in Australia.

Key takeaways

Hamburg 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 Hamburg chicken to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hamburg chicken from memory before moving on to harder problems.

Reference excerpt

The Hamburg, Dutch: Hollands hoen, German: Hamburger, is a Dutch breed of chicken. The name may be spelled Hamburgh in the United Kingdom and in Australia.

History The history and origins of the Hamburgh are not known. The gold-pencilled and silver-pencilled colour varieties appear to be of Dutch origin, and show some similarity to the Assendelfter. Other varieties appear to have developed in the United Kingdom, particularly in the counties of Lancashire and Yorkshire.

Characteristics The Hamburg is a small or medium-sized breed. For most colour varieties, cocks weigh 2–2.5 kg and hens about 1.6–1.8 kg or 1.5–2 kg; weights for the pencilled varieties are lower, at about 1.5–1.7 kg and 1.2–1.4 kg respectively.. Weights for bantams are roughly 700–1000 g for cocks and 600–800 g for hens. The standard ring sizes are 16 mm for cocks and 15 mm for hens, but for the pencilled variants are 15 mm and 13 mm respectively. Five different colour varieties are recognised by the Poultry Club of Great Britain: silver-spangled, gold-spangled, silver-pencilled, gold-pencilled and black. The same five are included in the American Standard of Perfection, with the addition of the white. The Entente Européenne recognises these six and also the blue; a further five are listed but not recognised: citron-pencilled, gold-white-pencilled, gold-blue-pencilled, cuckoo and red.

Use The Hamburgh is bred principally for exhibition. Hens lay approximately 120 or 170 white eggs per year, with an average weight of some 50 or 56 g; bantam hens lay some 130 or 140 eggs weighing about 30 or 35 g.

Worked examples

Example 1 — a first encounter with Hamburg chicken

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

In research: Hamburg 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 Hamburg 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: Hamburg chicken is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal breeds on the GEH Red List, Animal breeds on the RBST Watchlist, Chicken breeds, so understanding it makes those chapters shorter.
In everyday life: Look for Hamburg 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.
