The chicken (Gallus domesticus) is a large and round short-winged bird, domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs; others are kept as pets or for cockfighting.

Chickens are common and widespread domestic animals, with a total population of 26.5 billion as of 2023, and an annual production of more than 50 billion birds. A hen bred for laying can produce over 300 eggs per year. There are numerous cultural references to chickens in folklore, religion, and literature.

A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing. Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity that had to be periodically recharged by dipping the tip of the pen into an inkwell. Today, such pens find only a small number of specialized uses, such as in illustration and calligraphy. Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens. Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph. All of these modern pens contain internal ink reservoirs, such that they do not need to be dipped in ink while writing.

Poultry () are domesticated birds kept by humans for the purpose of harvesting animal products such as meat, eggs or feathers. The practice of raising poultry is known as poultry farming. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails, and turkeys). The term also includes waterfowls of the family Anatidae (ducks and geese) but does not include wild birds hunted for food known as game or quarry.

Recent genomic studies involving the four extant junglefowl species reveals that the domestication of chicken, the most populous poultry species, occurred around 8,000 years ago in Southeast Asia. This was previously believed to have occurred around 5,400 years ago, also in Southeast Asia. The process may have originally occurred as a result of people hatching and rearing young birds from eggs collected from the wild, but later involved keeping the birds permanently in captivity. Domesticated chickens may have been used for cockfighting at first and quail kept for their songs, but people soon realised the advantages of having a captive-bred source of food. Selective breeding for fast growth, egg-laying ability, conformation, plumage and docility took place over the centuries, and modern breeds often look very different from their wild ancestors. Although some birds are still kept in small flocks in extensive systems, most birds available in the market today are reared in intensive commercial enterprises.

Together with pork, poultry is one of the two most widely-eaten types of meat globally, with over 70% of the meat supply in 2012 between them; poultry provides nutritionally beneficial food containing high-quality protein accompanied by a low proportion of fat. All poultry meat should be properly handled and sufficiently cooked in order to reduce the risk of food poisoning. Semi-vegetarians who consume poultry as the only source of meat are said to adhere to pollotarianism.

Pride is defined by the Merriam-Webster dictionary as "reasonable self-esteem" or "confidence and satisfaction in oneself." The Oxford dictionary defines it as "the quality of having an excessively high opinion of oneself or one's own importance." Pride may be related to one's own abilities or achievements, positive characteristics of friends or family, or one's country. Richard Taylor defined pride as "the justified love of oneself," as opposed to false pride or narcissism. Similarly, St. Augustine defined it as "the love of one's own excellence," and Meher Baba called it "the specific feeling through which egotism manifests."

Philosophers and social psychologists have noted that pride is a complex secondary emotion that requires the development of a sense of self and the mastery of relevant conceptual distinctions (e.g. that pride is distinct from happiness and joy) through language-based interaction with others. Some social psychologists identify the nonverbal expression of pride as a means of sending a functional, automatically perceived signal of high social status.

Pride may be considered the opposite of shame or of humility, sometimes as proper or as a virtue and sometimes as corrupt or as a vice. With a positive connotation, pride refers to a content sense of attachment toward one's own or another's choices and actions, or toward a whole group of people and is a product of praise, independent self-reflection and a fulfilled feeling of belonging. Other possible objects of pride are one's ethnicity and one's sex identity (for example, LGBTQ pride). With a negative connotation, pride refers to some foolishand with corrupt irrational sense of one's personal value, status, or accomplishments used synonymously with hubris or vanity.

While some philosophers such as Aristotle (and George Bernard Shaw) consider pride (but not hubris) a profound virtue, some world religions consider pride as a fraudulent form of sin, as stated in Proverbs 11:2 of the Hebrew Bible. In Judaism, pride is called the root of all evil. When viewed as a virtue, pride in one's abilities are known as virtuous pride, greatness of soul, or magnanimity, but when viewed as a vices, it is often known to be self-idolatry, sadistic contempt or vainglory.
