Question: 1 / 515

What is the hatchability percentage if 180 chicks hatch from 200 eggs?

80%

90%

To determine the hatchability percentage, you need to calculate the ratio of the number of chicks hatched to the total number of eggs set. This can be expressed using the formula:

Hatchability Percentage = (Number of Chicks Hatched / Total Number of Eggs) × 100

In this case, 180 chicks hatched from a total of 200 eggs. Using the formula:

Hatchability Percentage = (180 / 200) × 100

This simplifies to:

Hatchability Percentage = 0.9 × 100 = 90%

Thus, the hatchability percentage is 90%. This indicates a successful hatch rate, suggesting that the incubation conditions were likely optimal and conducive to achieving a high percentage of viable chicks. Understanding hatchability is crucial for evaluating the effectiveness of incubation techniques and the overall health of the breeding stock.
