Hen house

A chicken coop or hen house is a small house where female chickens are kept safe and secure. there are nest boxes found inside the hen houses for egg-laying and perches on which the birds can sleep.

A chicken coop usually has an indoor area where the chickens can sleep and nest as well as an outdoor area where chickens will feed and spend the majority of the day. Inside the chicken coop are dropping boards or litter (such as straw) to collect chicken feces. A chicken coop should be cleaned after every two to three weeks and the litter shifted every day, like a cat's litter box. A coop should be locked at night with all the chickens inside it, so that the chickens are protected from predators.

A coop may have an outdoor run. Both the inside and outdoor floors of a chicken coop are often strewn with a loose material such as straw or wood chips to deal with chicken droppings and to allow for easier cleanup.

The purpose of a chicken coop is to protect chickens from bad weather - heat, cold, wind and rain and secure them from predators. One method to protect chickens is to put an isolation material between two layers of wood or bricks. Because chickens don't like heat, windows should be oriented in such a way as to prevent overheating. Proper ventilation is also important to protect the chickens from overheating and infectious bronchitis. Another purpose for chicken coops is to protect the hens from predators--especially foxes and cats. The hens can be released outside by daylight but should be locked in a coop at night.

There is a long-standing controversy over the basic need for a chicken coop. One philosophy, known as the "fresh air school" is that chickens are mostly hardy but can be brought low by confinement, poor air quality and darkness, hence the need for a highly ventilated or open-sided coop with conditions more like the outdoors, even in winter. However, others who keep chickens believe they are prone to illness in outdoor weather and need a controlled-environment coop. This has led to two housing designs for chickens: Fresh-air houses with wide openings and nothing more than wire mesh between chickens and the weather (even in Northern winters), or closed houses with doors, windows and hatches which can shut off most ventilation.

Backyard coops are small and often enclosed within a fenced area (sometimes bounded by chicken wire) thus creating a more natural living environment, one in which the chickens can not only roam freely, but also peck and hunt for insects. If this kind of "yarding" is both floorless and reasonably mobile it is called a chicken tractor. Many people, especially those in rural areas, keep a small flock of chickens for themselves from which they harvest both eggs and meat.
