poultry
Synonym discussion
Sense: noun/1
For sense 1, poultry is the general word for chickens, ducks, geese, turkeys, and similar birds that people keep for eggs or meat. Chicken is much narrower: it usually names one type of bird, not the whole group. Fowl can overlap with poultry, but it often sounds more formal, technical, or old-fashioned. Livestock is broader than all of them, because it includes larger farm animals such as cows, pigs, and sheep as well as poultry. So a farm report may discuss poultry numbers, a cook may say chicken is cheaper this week, and an agriculture class may study poultry separately from other livestock.
Etymology
English got poultry from an Old French word for young domestic birds. That French word was built from poulet, meaning a young chicken, and it goes back to Latin pullus, a word for a young animal or chick. In English, the meaning later settled on birds raised for eggs or meat, and also the meat from those birds.
