Enter the total number of eggs placed in an incubator and the total number of eggs hatched into the calculator to determine the hatch rate.

## Hatch Rate Formula

The following formula is used to calculate the hatch rate of a set of eggs.

HR = EH / EI * 100

• Where HR is the hatch rate (%)
• EH is the total number of eggs that hatched
• EI is the total number of eggs place in the incubator

To calculate the hatch rate of a chicken, divide the number of eggs hatched by the number of eggs in the incubator, then multiply by 100.

## What is a hatch rate?

Definition:

A hatch rate is defined as the total percentage of eggs that hatch from a given set that have been placed in an incubator.

## How to calculate hatch rate?

Example Problem:

The following example outlines how to calculate a hatch rate.

First, determine the total number of eggs placed into the incubator. In this example, the total number of eggs is counted to be 50.

Next, count up the number of eggs that end up hatching. For this problem, 40 of the eggs hatch.

Finally, calculate the hatch rate using the formula above:

HR = EH / EI * 100

HR = 40/50* 100

HR = 80%
