Introduction:

The term “hen” refers to female chickens and other female birds belonging to the Galliformes order. Chickens are omnivorous birds that eat insects, reptiles, seeds, and grains, among other things.

The scientific name of hen:

The biological term for hens is Gallus gallus domesticus, according to binomial nomenclature. It deviates from the traditional naming of organisms, which employs two names: a family name and a genus or species name. As a result, binomial nomenclature was coined. A hen’s scientific name is trinomial, with the first name representing the genus and the other two names representing the specific name. All of the names of a creature’s binomial nomenclature are written in Latin.
