An incubator is a special device that helps keep eggs warm and safe until they hatch. It mimics the conditions a mother bird provides, maintaining the right temperature and humidity. This is important for the developing embryos inside the eggs, whether they belong to chickens, ducks, or other birds. In the business world, an incubator serves a different purpose. It supports new companies, often called startups, by providing resources like office space, mentorship, and funding. This helps entrepreneurs turn their ideas into successful businesses, much like how an egg incubator helps hatch healthy chicks.
