Incubation is the time between which two stages?

Incubation is the time between which two stages?

• A. breeding and laying
• B. laying and hatching
• C. none are correct
• D. incubation and laying

Answer: (D)

Incubation is the period of egg development from when the egg is laid (and fertilized) until the chick hatches. That makes the incubation interval the time between laying and hatching. The other options describe different stages or mix stages in ways that don’t define a time span: breeding and laying occur before the egg is laid; laying and hatching would be completing the interval but isn’t the standard way to define incubation; and “none are correct” isn’t accurate because there is a clear time frame. In hatchery practice, this incubation duration is what you manage through temperature, humidity, and turning to support successful hatching.
