Chickens need the same things other creatures need.......food, water, and shelter from predators & the weather.

A coop
Yes. A chicken needs to roost at night and have shelter from both predators and the elements. Shelters do not need to be elaborate, just safe and protect them from the wind and rain. It also helps you find eggs if you provide a safe haven for the flock to gather.
Food, water and shelter fro the elements.
Chickens do best in moderate temperatures. The are adaptable to extremes, but need shelter from the severe cold and heat. Temperatures from 50F to 80F are preferred as far as laying eggs. Day old chicks need the higher temperatures only until their feathers are fully formed.
Chickens can be raised just about anywhere. If you provide safe shelter, good nutrition and plenty of clean fresh water a chicken will be happy.
The place where chickens are kept is called a coop. Chickens need shelter and a place to roost/ sleep that is out of the weather and safe from predators. Chicken quickly learn where this safe home is and will gather as a flock just after dusk, free range chickens will spend the night in the coop and emerge at dawn looking for food.
Because its shelter we need shelter to survive.
Yes, chickens sleep at night. All creatures need to sleep. Chickens roost, which means to get off the ground and perch on something above ground level. This allows them to sleep in comparative safety. Chickens will seek the safety of the chicken coop or any shelter provided and settle down until just prior to daylight the following morning.
You can house 16 chickens in an 8' x 8' chicken coop if the chickens are also allowed to free range or have access to an outdoor scratch yard. In this case, they only need about four square feet apiece as the coop itself is used primarily for nesting, roosting at night, and shelter in bad weather. If the coop is the chickens' only environment and they do not have outdoor access, they will need about 10 square feet each, meaning that a hen house of this size could comfortably house six chickens.
Many chickens and other farm raised bird are kept in coops.
