Farms can be large or small. A large farm might be mixed, poultry, beef, or dairy! They can have thousands of acres of land and hundreds of animals. These farms might have several employees that they hire for the whole year, not just for seasonal work. 98% of all farms are family farms, even if they are large!
Most large farms are family operated and they hire employees to help with all of the work that is required to run the operation.
