Incubation duration and temperature
Parrot egg incubation periods can vary by breed but are typically between 24-28 days. Some parrot breeds can hatch in as little as 18 days. Research your specific breed to find out how long your egg will need to be incubated. This article assumes a 24 day hatching cycle, so you may need to adjust based on your breed.
Under natural conditions, the most important factor in successful parrot egg incubation is heat.
