Difference Between Chicken and Hen

The difference between a chicken and a hen is in their gender.  Chickens are members of the fowl family of birds.  They are a subspecies of the red and the grey jungle fowl. It is correct to call a hen a chicken, but to be more specific the chicken can only be called a hen if it is female and of egg laying age.  Therefore outwardly a chicken can look and sound like a hen, but the hen is a female chicken and one that is ready to lay eggs.  A person who is not knowledgeable in the ages and stages of poultry might call a hen a chicken or a chicken a hen.

What is a Chicken?

A chicken is defined as a common domestic fowl.  The term chicken does not specify the gender of the bird.  Chicken is the name of the species like cat or dog.  Before a chicken becomes a hen it is called a pullet.  A pullet has not quite reached the point of lay.  That is the time the female chicken is ready to start laying eggs.  During this time it is correct to call the bird a chicken or a pullet.

What is a Hen?

A hen is a mature chicken ready to lay eggs.  A fully grown female chicken, of egg laying age is a hen.  The female chicken or hen can reach this stage at different times, but it is usually when she reaches a year of age.  Once the first egg has been laid the pullet graduates to being a hen.  She is accepted by the rest of the more mature hens in the coop. There are some differences of opinion with regard to the maturity of the chicken and some say the transition takes place at one year of age and not when the first egg is laid.  Another way of gauging if the chicken is a hen is through the cartilage or breast bone.  If this bone is still soft the chicken is not yet mature enough to be called a hen.  A hen will get to egg laying age and lay eggs regardless of the presence of a rooster.  Basically a hen is a mature adult female chicken capable of laying eggs.
