What is a common mistake in hatching that can lead to chick dehydration?

1. Inadequate humidity

2. Excessive heat

3. Chicks are in the hatchery for too long

4. Insufficient ventilation

The correct answer is: Chicks are in the hatchery for too long

A common mistake in hatching that can lead to chick dehydration is inadequate humidity. Proper humidity levels during the incubation and hatching process are critical for ensuring that the eggs lose the right amount of moisture. If the humidity is too low, the moisture evaporates excessively from the eggs, leading to dehydration of the developing chicks. Low humidity can cause the inner membranes to dry out, making it difficult for chicks to hatch successfully. When chicks do not have sufficient moisture, they can become stuck in the eggs, and their body systems can be adversely affected, resulting in dehydration. Maintaining the correct humidity range during hatching is vital for promoting healthy development and successful hatching rates. While the other options may also have implications for chick health, the specific link between inadequate humidity and dehydration emphasizes the need to monitor and maintain proper moisture levels in the hatchery environment.
