The term 'Henhouse Feature' refers to two components of a henhouse, which is a structure used to house chickens. The first component is the 'NEST', which is a place where chickens lay their eggs. The second component is the 'ROOST', which is a perch or platform where chickens sleep. Both the NEST and the ROOST are essential features of a henhouse, providing the chickens with a safe and comfortable environment.
