Gallus gallus domesticus
The term “Hen” is used to denote a female chicken or other female birds in the order Galliformes. In this article, we shall explore more about the chicken (Gallus gallus domesticus).
Chickens are one of the most common domestic animals in the world, with an estimated total population of 23.7 billion as of 2018. Chickens are primarily rearer for their meat and eggs. They are also kept as pets and for special events – such as for cockfighting.
Chickens are omnivores, feeding on seeds, insects and even small lizards. The lifespan of the average chicken is about 5 to 10 years. Chickens live in flocks, and are gregarious. Chickens also follow a hierarchical system of social organization, where dominant individuals will have priority access over food as well as nesting locations.
Modern chickens are descendants of the red jungle fowl (Gallus Gallus), but are technically classified as the same species. Digging deeper, the origins of the chicken can be traced back to a group of dinosaurs called the theropods, this means that the chicken is closely related to the now-extinct carnivore Tyrannosaurus rex. In fact, current research has shown that T.rex is about 58% genetically similar to a chicken.
