The incubator is an apparatus that is used to regulate environmental conditions such as temperature, humidity and turning for successful hatching of the fertile eggs placed in an enclosure. It is often used for growing bacterial cultures, hatching eggs artificially, or providing suitable conditions for a chemical or biological reaction. The incubator is recorded being used to hatch bird and reptile eggs. It lets the fetus inside the egg grow without the mother needing to be present to provide the warmth. Chicken eggs are recorded to hatch after about 21 days, but other species of birds can take a longer or shorter amount of time. Incubators are also used to raise birds.
An incubator should be able to set the perfect environment and condition for an egg to incubate because it regulates the factors such as temperature, humidity, and turning the eggs when necessary, so the egg is incubated properly because it plays the role of the hen in its natural state. The incubator also allows the egg to incubate while eliminating the external threats that could possibly harm the eggs.
