Incubating and viewing plates. Incubating the plates to promote growth of microbes is an essential part of any microbiology investigation. Incubating in aerobic conditions, and below human body temperature, reduce the risk of encouraging microorganisms (particularly bacteria) that could be pathogenic to humans.
Some species begin incubation with the first egg, causing the young to hatch at different times; others begin after laying the second egg, so that the third chick will be smaller and more vulnerable to food shortages. Some start to incubate after the last egg of the clutch, causing the young to hatch simultaneously.
