Look over our Incubating and Hatching Eggs Forum to read about the different types of incubators and how well they work. The other method to hatch eggs is to owm a hen that has gone broody. The chances are that all of this farmer's eggs are fertile Or you could ask whether he happens to have a broody, and could you borrow her long enough to hatch eggs. All she needs is a small safe area, a nest, food and water, and 21 days. There are also lots of threads in that same Incubating forum about broodies.
Yhere is also a lot of information in our Learning Center at the top of the page, under Hatching Eggs and Raising Chicks. Good luck!
