Poultry incubators and hatchers are machines used to artificially incubate and hatch chicken eggs. They provide a controlled environment for the eggs to develop and hatch, with the appropriate temperature, humidity, and ventilation.

Incubators typically have several features including temperature control, humidity control, ventilation, and egg turning. They are designed to maintain a consistent temperature and humidity level, while also providing fresh air to the developing embryos. The egg turning feature helps to prevent the embryo from sticking to the inside of the shell and promotes even development.

Hatchers are used to provide the ideal conditions for the eggs to hatch. They are designed to provide the necessary temperature, humidity, and ventilation to help the chicks hatch safely. They usually have racks to hold the eggs and are designed to allow easy access to the chicks once they hatch.

Both incubators and hatchers can be used for a variety of poultry species, including chickens, ducks, geese, and turkeys. They can range in size from small, tabletop models to large commercial units capable of hatching thousands of eggs at a time.
