The formula to calculate the Hatch Rate (HR) is:
\[ HR = \frac{EH}{EI} \times 100 \]
Where:
A hatch rate is defined as the total percentage of eggs that hatch from a given set that have been placed in an incubator.
Let's assume the following values:
Using the formula to calculate the Hatch Rate (HR):
\[ HR = \frac{80}{100} \times 100 = 80\% \]
The Hatch Rate (HR) is 80%.
