Origin Not an ancient creature, but a translation
The cockatrice is an accident of language as much as a creature. Latin translations of scripture used calcatrix to render a Hebrew word for a venomous snake, and the term drifted; by the later Middle Ages a cockatrice was a beast hatched from an egg laid by a cock and brooded by a toad or serpent, with a rooster's head and comb, wings and a serpent's tail, killing by sight or touch. It merged almost completely with the basilisk, and English writers used the two names interchangeably, which is why illustrations of the classical basilisk show a rooster. Its most stable existence is heraldic, where it is drawn to a fixed pattern and distinguished from the wyvern.

Medieval translators rendering the Latin basiliscus and Old French cocatriz let the two merge until the rooster-headed form became the standard image in bestiaries and later heraldry. 2 Attestation

Domain / FunctionDomain born from translation: Latin calcatrix rendered a Hebrew word for a venomous snake in scripture, drifting by the late Middle Ages into a beast hatched from a cock's egg, most stably preserved today in heraldry. 1 Cult
Attributes and IconographyThe cockatrice is depicted as a two legged, dragon-like creature crowned with a rooster's head, said to hatch from a yolkless egg laid by an aging cock and incubated by a serpent or a toad. Its gaze or breath alone is fatal, and the standard remedy in bestiary tradition is to trick it into seeing its own reflection, or to rely on the crow of a rooster, said to kill it outright. 1 Learn More
A Creature Born from a Mistranslation
The cockatrice is an accident of language as much as a creature. Medieval Latin used calcatrix (from a verb "to tread") to render a Greek word for the ichneumon, and versions of scripture used it and related words for Hebrew terms for venomous snakes; the word drifted, and by the later Middle Ages a "cockatrice" was understood as a beast hatched from an egg laid by a cock (rooster) and brooded by a serpent or toad, killing with its glance and breath. In this it merged almost completely with the basilisk.
English translations of the Bible, including the King James Version at Isaiah 11:8 and Jeremiah 8:17, print "cockatrice" where the Hebrew has a poisonous serpent, embedding the mistranslation in scripture for English readers. In heraldry the cockatrice took a fixed and vivid form: a two-legged winged creature with the head, comb and wattles of a rooster and the barbed tail of a serpent, distinct in blazon from the wyvern. It is thus a creature assembled almost entirely from philological confusion and heraldic convention, with no coherent mythology of its own behind it.
A Creature the English Bible Put into Circulation
The cockatrice owes much of its currency in English to translation. Early modern English Bibles, including the King James version, use the word to render Hebrew terms for a venomous snake at several points in Isaiah, Jeremiah and Proverbs, most memorably in the passage where a weaned child puts its hand on the cockatrice den. Later English versions replace it with adder or viper, because the Hebrew names a snake and nothing more.
The effect of those two centuries of use was to give a bestiary creature scriptural standing. A reader who met the word in church and again in a herbal or a book of wonders had no reason to think the two were different things, and the cockatrice acquired the authority of the text it had been inserted into. That is one of the clearer examples of a translation choice creating a creature rather than describing one.
The heraldic cockatrice is a separate track and it is precise where the folklore is not. Blazon gives it a cock's head, wattles and comb, a dragon's wings and body, and a barbed serpent tail, and heralds distinguish it from the basilisk, which in strict usage has a dragon's head at the end of its tail as well. Outside the college of arms nobody has ever kept that distinction, and the two words remain interchangeable in ordinary use.

Derived From
The cockatrice enters English usage as a translator's name for the creature Latin authors call basiliscus, described in works such as the Physiologus, and it picks up the cockerel-hatched-egg origin story along the way from later medieval bestiary tradition. The derivation from basiliscus to cockatrice is a matter of translation and textual history that is well documented rather than contested among students of medieval bestiaries.

The classical serpent with the diadem-like mark on its head was progressively conflated with the cock-hatched creature of medieval legend until the two names were used interchangeably.
