If you’re considering keeping backyard chickens then you’ll need to understand some basic terminology and lingo. So, let us answer one of the most common questions first. What’s the difference between a chicken and a hen?

Separate your chickens from your hens!

Let’s look at these widely used poultry terms to understand their meaning and where they come from:

  • What is a chicken?

A chicken is an alternate name for Gallus gallus Domesticus the domesticated bird species that we are all familiar with and is kept around the world for its meat and eggs.

Where does the word chicken come from?

The word chicken is derived from the old English word ‘cicen‘which is related to a number of older European forms in languages such as:

  • Dutch kiekijen
  • Swedish kyckling
  • German Küken

In the middle ages, the term chicken was simply a casual term for a group of young domestic fowl or chicks. The -en ending was used much like it is for words like children or oxen. Over the centuries the word chicken stuck and superseded the Germanic word fowl, to apply to birds off either sex and all ages.

  • So what is a hen?

The word hen denotes a female chicken that has reached sexual maturity and is laying eggs. For most female chickens this is between 16 and 20 weeks of age.

This means that a hen is simply a mature female chicken and not a different species or type of fowl.

This word meaning a female domestic fowl has its origins in a number of Western European tongues:

  • West Germanic hannjo
  • Frisian henn
  • Middle Dutch henne
  • High German henna

It is actually a feminized version of the Old English word hanan which is male chicken or cockerel and derived from a more ancient word, kan, to sing.

Now we have corrected our ‘fowl’ language, let’s delve into the origins of these useful birds who have made themselves a household name across the globe.

The illustrious ancestry of the chicken

The origins of the humble backyard hen are far more exotic than you may realize. Gallus gallus Domesticus can be traced over thousands of years of breeding to the striking Red Jungle Fowl, Gallus gallus.

These elusive tropical birds hail from the jungle depths of southeastern Asia where unlike their domesticated relatives, they tend to avoid human interaction.

They make the margins of dense vegetation their habitat, foraging fruits, seeds, insects, and grubs and darting undercover if predators approach.

What these fowls lack in size, they make up for in an eye-catching display. They are smaller than most domestic breeds of chicken. Males, in particular, have a colorful plumage with reds, greens, and metallic tones alongside vivid red wattles. Females are plain but also sport long tail feathers.

Red Jungle Fowl live in groups usually headed by dominant and lesser males and females who breed only at certain times of the year. During these periods, which range from winter through early spring, females lay an egg per day.

From the Indonesian jungle to your backyard

Thousands of years of breeding and domestication have taken the Red Jungle Fowl and related species and produced the larger and more fertile chickens we know today.

Interestingly, the vast number of modern breeds with distinctive physical characteristics come from minor genetic variations but the Red Jungle Fowl and other common ancestors remain the major contributors of genetic material.

It appears that the Jungle Fowl caught the eye of man over 7,000 years ago with flocks of these productive and tasty birds that were easy to house and breed being kept by Indian villagers. They found out that when these fowl were plied with abundant food they would breed prolifically, upregulating their egg production to almost daily!


Ancient writings from Middle Eastern antiquity spoke of a bird that lays an egg every day and remains of domestic poultry have been found as far back as 4000 years ago in excavations of the Indus Valley.

Due to their compact size and ease of care, these early domestic chickens are likely to have moved with trade and migration over the centuries. They certainly were a feature of animal husbandry in major civilizations such as Ancient Egypt, and the Greek and Roman Empires.

Genetic studies looking at the origins of the chicken have found that their ancestors were surprisingly widespread with ancient remains of household hens being found in places as disparate as the Dominican Republic, Pacific Islands, and Eastern Europe.

Contemporary breeding

Chickens fell out of favor in Europe in the later Middle Ages, but the practice of keeping hens recovered with the expansion of trade and exploration from the 17th century onwards.

In Asia, chickens continued to be bred and ornamental breeds were carried back to Europe by mariners and merchants alongside their wares. In the 19th century, a resurgence in interest in animal husbandry in the West led to a renewed focus on the chicken for intensive production of meat and eggs, and efforts to breed chickens for this purpose began in earnest.

A notable example is the Rhode Island Red, a large American breed developed in the 19th century from Oriental and Italian chicken breeds for superior meat and egg production.

Globally, contemporary chicken production is a highly industrialized and commercial operation, but the rearing and keeping of hens for eggs, in particular, is still appreciated by many households.

Chickens make great pets and enthusiasts like chicken fanciers pay great attention to the specific features and temperaments of the hundreds of breeds that exist today.
