Everyone remember we use incubators to increase the success rate for hatching, minimize any errors possible, as well as shorten the time it takes for hatching. But in the wild, temperatures fluctuate, humidity fluctuates, and I can almost guarantee that at least 80% of the eggs hatch.

It's just like certain plants that we grow in a controlled environment to yield their products sooner. Sure if you raise them outside they'd grow and produce. But in a controlled environment you can manipulate everything to your benefit.
