Opening Incubator During Lockdown: What Happens?

Have you ever wondered what would happen if you opened an incubator during lockdown? It's a question that might pop into your head, especially if you're new to hatching eggs. Incubators are designed to provide a controlled environment, mimicking the conditions a mother hen would naturally provide. This includes consistent temperature, humidity, and regular turning of the eggs. When these conditions are disrupted, it can have a significant impact on the developing embryos. In this article, we'll dive deep into the potential consequences of opening an incubator during lockdown and what you can do to minimize any negative effects.

Understanding the Lockdown Period

Before we delve into the consequences, let's first understand what the lockdown period is and why it's crucial for successful hatching. The lockdown period is the final stage of incubation, typically the last three days before the eggs are due to hatch. During this time, you stop turning the eggs and increase the humidity levels inside the incubator. This stage is critical because the chicks are positioning themselves for hatching and absorbing the remaining yolk sac, which provides them with essential nutrients for their first few days of life. Maintaining stable conditions during lockdown is vital for a successful hatch.

Why Lockdown is Critical

The lockdown period is a critical phase in the incubation process for several reasons. First and foremost, it allows the chicks to get into the correct hatching position. Inside the egg, the chick needs to orient itself so that its beak is facing the air cell, which is a pocket of air located at the blunt end of the egg. This positioning is crucial because the chick needs to pip, or break through the air cell, to take its first breath of air. Disrupting the eggs during this time can prevent them from getting into the correct position, potentially leading to hatching difficulties or even death. Secondly, the higher humidity during lockdown helps to soften the shell membrane, making it easier for the chicks to hatch. If the humidity is too low, the membrane can become tough and leathery, making it difficult for the chick to break through. Lastly, the undisturbed environment during lockdown allows the chicks to fully absorb the yolk sac. This yolk sac provides the chick with the necessary nutrients and energy reserves for the first 24-72 hours of its life, giving them a head start before they need to start eating and drinking. Any disturbance during this crucial time can compromise their ability to absorb the yolk sac fully, which can weaken them and decrease their chances of survival.

The Immediate Impact of Opening the Incubator

So, what happens the moment you open the incubator during lockdown? The most immediate impact is a drop in temperature and humidity. Incubators work hard to maintain a very specific environment, and even a brief opening can cause a significant fluctuation. This disruption can be stressful for the chicks and can affect their development. Imagine being in a warm, cozy room and suddenly having the door flung open on a cold day – that’s similar to what the chicks experience when the incubator is opened.

Temperature Fluctuations

Temperature is arguably the most critical factor in successful incubation. The ideal temperature for most poultry eggs is around 99.5°F (37.5°C). During lockdown, maintaining this temperature is even more crucial because the chicks are in their final stages of development and are particularly sensitive to temperature changes. When you open the incubator, the warm air inside rushes out, and cooler room air rushes in. This can cause the temperature to drop several degrees in a matter of seconds. While the incubator will eventually reheat, the temperature fluctuation can have detrimental effects on the developing chicks. Temperature drops can slow down the hatching process, weaken the chicks, and in severe cases, even lead to death. Chicks that are exposed to significant temperature fluctuations may hatch later than expected, be weaker, or have deformities. Therefore, it's essential to minimize temperature fluctuations during lockdown to ensure a healthy hatch.

Humidity Changes

Humidity is the second key factor in a successful hatch, especially during lockdown. The ideal humidity level during lockdown is typically around 65-75%, depending on the type of bird you're hatching. This higher humidity level helps to prevent the membranes inside the egg from drying out and becoming tough, making it easier for the chicks to pip and hatch. When you open the incubator, the humid air inside escapes, and drier room air enters. This can cause the humidity level to drop quickly, which can lead to several problems. If the humidity is too low, the membranes can become dry and shrink-wrapped around the chick, making it difficult or impossible for the chick to break free. This condition, known as “sticky chick,” is a common cause of hatching failure. Additionally, low humidity can cause the chicks to lose too much moisture, leading to dehydration and weakness. Maintaining proper humidity during lockdown is therefore crucial for a smooth and successful hatch. Opening the incubator, even briefly, can disrupt this delicate balance and jeopardize the outcome.

Potential Long-Term Consequences

The short-term disruptions caused by opening the incubator can also lead to long-term consequences for the chicks. These can range from weakened immune systems to increased mortality rates. The stress caused by temperature and humidity fluctuations can have a ripple effect on the chicks' overall health and well-being.

Weakened Immune Systems

One of the most significant long-term consequences of opening the incubator during lockdown is a weakened immune system in the hatched chicks. The stress caused by temperature and humidity fluctuations can compromise their immune systems, making them more susceptible to diseases and infections. Chicks are particularly vulnerable in their first few weeks of life, as their immune systems are still developing. If they are exposed to stress during the critical hatching period, their immune systems may not develop properly, leaving them more prone to illness. This can lead to increased mortality rates and the need for more intensive care and management. A strong immune system is crucial for the long-term health and survival of chicks, and maintaining a stable environment during lockdown is vital for supporting their immune system development.

Delayed Hatching and Deformities

Opening the incubator during lockdown can also lead to delayed hatching and an increased risk of deformities. Temperature fluctuations can slow down the development of the chicks, causing them to hatch later than expected. This delay can be problematic because the chicks are relying on the yolk sac for nutrition, and if they hatch too late, the yolk sac may be depleted, leaving them weak and undernourished. Additionally, temperature fluctuations can disrupt the delicate processes involved in chick development, increasing the risk of deformities such as crooked toes, spraddle legs, or other physical abnormalities. These deformities can affect the chicks' ability to walk, eat, and thrive, potentially leading to a lower quality of life. Maintaining a stable environment during lockdown is therefore crucial for ensuring proper development and minimizing the risk of hatching delays and deformities.

Increased Mortality Rates

Perhaps the most severe long-term consequence of opening the incubator during lockdown is an increased mortality rate. The combined effects of temperature and humidity fluctuations, weakened immune systems, delayed hatching, and deformities can significantly increase the likelihood of chicks dying either during or shortly after hatching. Chicks that are stressed during the hatching process are less likely to be vigorous and healthy, making them more vulnerable to various health issues. They may also have difficulty breaking out of the shell, leading to exhaustion and death. Reducing mortality rates is a primary goal for anyone hatching eggs, and avoiding disturbances during lockdown is a key step in achieving this goal. By maintaining a stable and optimal environment, you can give your chicks the best possible start in life and increase their chances of survival.

Exceptions and Minimizing Impact

While it's generally best to avoid opening the incubator during lockdown, there are some exceptions. For example, you might need to add water to maintain humidity levels or remove hatched chicks to prevent them from disturbing unhatched eggs. In these situations, the key is to minimize the time the incubator is open and to work as quickly and efficiently as possible.

Adding Water

Maintaining adequate humidity is crucial during lockdown, and sometimes this requires adding water to the incubator. If your incubator has an external water fill, this is ideal as it allows you to add water without opening the incubator. However, if you need to open the incubator to add water, do so quickly and try to minimize the amount of time the door is open. Use warm water to avoid dropping the temperature too much, and close the incubator as soon as possible. Some incubators have humidity pumps that automatically regulate humidity levels, which can help to minimize the need for manual adjustments. Consistent humidity levels are key to a successful hatch, so be prepared to monitor and adjust as needed, but always prioritize minimizing disturbances.

Removing Hatched Chicks

Once chicks start hatching, it’s tempting to open the incubator to admire them. However, it’s best to leave them inside until the hatch is complete. Hatched chicks can stay in the incubator for up to 24 hours without food or water, as they are still absorbing nutrients from the yolk sac. If you need to remove hatched chicks to prevent them from disturbing unhatched eggs or if the incubator is becoming overcrowded, do so carefully and quickly. Have a brooder box prepared with a heat source, such as a heat lamp or brooder plate, to keep the chicks warm. Transfer the chicks gently and try to avoid exposing them to drafts or significant temperature changes. It’s generally best to wait until most of the chicks have hatched before removing them, as this minimizes the number of times you need to open the incubator.

Candling Eggs During Lockdown

Candling eggs is a method of using a bright light to check the development of the embryo inside the egg. While candling is typically done before lockdown to remove any infertile eggs, some people may be tempted to candle eggs during lockdown to see how the chicks are progressing. However, it’s generally best to avoid candling eggs during lockdown unless absolutely necessary. Removing the eggs from the incubator, even briefly, can disrupt the temperature and humidity levels. Additionally, the bright light can be stressful for the developing chicks. If you do need to candle eggs during lockdown, do so quickly and carefully, and try to minimize the amount of time the eggs are out of the incubator. Only candle if necessary and make sure to handle the eggs gently and return them to the incubator as soon as possible.

Best Practices for a Successful Lockdown

To ensure a successful hatch, it's crucial to follow best practices during the lockdown period. This includes maintaining stable temperature and humidity levels, avoiding unnecessary disturbances, and preparing for the hatch.

Maintaining Stable Conditions

The most important aspect of lockdown is maintaining stable conditions inside the incubator. This means keeping the temperature and humidity levels as consistent as possible. Use a reliable thermometer and hygrometer to monitor the conditions inside the incubator, and make adjustments as needed. Avoid placing the incubator in a drafty area or near a window where it can be exposed to temperature fluctuations. If you live in an area with significant temperature variations, consider using an incubator with a built-in temperature and humidity control system. Consistency is key during lockdown, so do everything you can to create a stable and controlled environment for the developing chicks.

Avoiding Unnecessary Disturbances

As we’ve discussed, opening the incubator during lockdown can have negative consequences. Therefore, it’s best to avoid unnecessary disturbances. This means resisting the urge to check on the eggs too frequently or to candle them during lockdown. If you need to make adjustments to the humidity or remove hatched chicks, do so quickly and efficiently. Minimize the time the incubator is open and try to avoid any sudden movements or vibrations that could disturb the eggs. The more stable and undisturbed the environment, the better the chances of a successful hatch.

Preparing for the Hatch

Before lockdown begins, make sure you are fully prepared for the hatch. This includes having a brooder box set up and ready to go, with a heat source, food, and water. The brooder box should be clean, dry, and draft-free, providing a safe and comfortable environment for the newly hatched chicks. You should also have a plan in place for what to do with the chicks once they hatch, whether you’re raising them for meat, eggs, or as pets. Proper preparation is essential for ensuring a smooth transition for the chicks from the incubator to the brooder and beyond. By having everything ready in advance, you can minimize stress and maximize the chances of a successful outcome.

Final Thoughts

Opening the incubator during lockdown can have significant consequences for developing chicks. While it's tempting to peek inside, maintaining a stable environment is crucial for a successful hatch. By understanding the risks and following best practices, you can minimize disturbances and give your chicks the best possible start in life. Remember, a little patience and diligence during lockdown can make all the difference in the health and vitality of your newly hatched chicks. So, resist the urge to open that incubator and trust the process – your fluffy friends will thank you for it!
