The result of highly dangerous magical experimentation, the Hyper-Chicken has become a feared predator of humanoids where it has been found.  Standing nearly 9 feet tall, hairless, with short, stubby legs, a thick torso, long clawed hands, and a long neck and human-like head, this aberration is known both for its fecundity, and the violent way it preys on humanoid targets.

Ultra Prolific Egg-Layers.  Derived from the common chicken,  the Hyper-chicken is known for its fecundity.  An adult hyper-chicken is able to produce a viable egg within seconds, which it lays through its mouth, an excruciating process that is both painful to the hyper-chicken, and horrifying to observers.  Many who have observed the process describe feelings of abject fear and revulsion, and many are forced to flee.  Oddly, the process of creating these eggs does not depend on nutrition or food intake, but rather survival.  Often when encountering a threat, or even substantial numbers of prey creatures, the hyper-chickens first instinct is to immediately lay an egg, increasing the chance of its species survival.

Resilient Eggs.  Hyper-chicken eggs are notoriously hard to break prior to hatching (which can occur in less than a minute).  Using fire to destroy the egg is ill-advised, and seems to speed up the hatching process.  Hyper-chickens are hatched as adults, and are fully capable of producing new eggs at birth, often as its first act.  Control of the species is predicated on immediate destruction of eggs using non-flammable means.

Violent Predators.  The Hyper-chicken will often seek out humanoid targets to prey upon.  When attacking, the Hyper-chicken will attempt to grab its prey in its claws and then regurgitate acid vomit into the preys mouth.  The acid dissolves the preys innards, which then are sucked out much like a spider.  This violent and gruesome manner of feeding is one of the reasons why this creature is considered a massive threat to all humanoids it encounters.
