The product that has been researched is egg turners for poultry. This product is used by chicken farmers all across the globe. The purpose behind an egg turner is so the farmer can use the turner when they are trying to hatch a large number of chicks without the use of hens. They use an incubator instead, and save money on feed and housing of the hens. Instead the cost comes from the use of electricity to heat the incubator and turn the eggs. The gestation period of a chicken is approximately 21 days (2); this begins when the egg is fertilized.
