A hen is a female chicken that is at least a year old.
The hen is housed in a coop.
As a result, the hen's shelter name is ‘coop’.
It is important to keep the hen in the chicken in order to protect them from predators and unfavorable environmental conditions.
Additionally, a decent coop allows hens to roost while upholding their social structure, which reduces territorial behavior that might result in conflict amongst the other hens.
