A chicken is a type of domesticated bird, while a hen refers to an adult female chicken. Chickens are a general term that includes both male and female birds, while hens are specifically female. Hens are usually kept for their eggs, which are used for both food and hatching other chickens. Chickens can also be kept as pets or for their meat.
Chickens have different breeds, and each breed has different characteristics. For example, some chickens lay more eggs than others. Hens typically lay one egg per day, while chickens can lay up to three eggs per day. Chickens also come in different sizes, colors, and shapes. Different breeds of chickens are also used for different purposes, such as for meat, eggs, or laying eggs for hatching other chickens.
