Poultry farmers raise chickens, ducks, geese, and turkeys. There are two types of chicken farms: one that raises the chickens for meat, and the other one that raises chickens for eggs.
Poultry barns have technology that needs to be managed, like these feeders and watering lines that can be raised as the chicks grow.
Large modern poultry farms will only raise one type of bird such as egg layers. Some small farmers might raise different breeds of chickens, turkeys, ducks, and geese. There are no big-scale duck and geese farms like there are for chickens and turkeys.
This is a modern turkey farm where feeders and watering lines run on the sides of the barns for the birds.
