A place where hens or poultry birds are kept; a chicken coop or henhouse.
From 'hen' (Old English 'henn') + '-ery' (suffix creating place nouns). The word has been in use since at least the 1700s for facilities dedicated to keeping domesticated fowl.
A 'hennery' sounds quaint and old-fashioned, but it reveals how people actually organized their farms—most families kept a separate structure just for hens because they were so economically important for eggs, making the word reflect real historical conditions.
