Nests are structures built by birds to house their eggs and young. ARKS are large boats or vessels used to transport animals. Cotes are small, enclosed shelters for domestic animals such as chickens and rabbits. Sheds are larger structures used to store tools and equipment, but can also be used to house animals.
