Description

The Jumbl Egg Incubator JUMBINCBT12 boasts a sleek and durable design, making it a reliable choice for both beginners and experienced poultry breeders. The incubator features a clear plastic window for easy observation of the eggs without disturbing them. It includes a digital display that shows the current temperature, humidity, and turning status. The device is equipped with an automatic alarm system that alerts you to any temperature or humidity deviations.

The incubator also comes with a built-in ventilation system to ensure proper airflow, which is crucial for healthy egg development. The turning mechanism is designed to gently rotate the eggs every two hours, mimicking the natural turning process of a brooding hen.

GETTING STARTED WITH YOUR INCUBATOR

Assembly

Install the rotating shaft by aligning the opening with the metal prong extending from the inside of the cover and firmly pressing it down into place.
Place the dividing strips into the egg tray so that your eggs will have at least 2-3 mm of space between them. You can arrange the dividers to make wide columns if you’re using larger eggs, and smaller columns if you’re using smaller eggs.
If you’re incubating eggs in an area where the ambient temperatures might fall below 68°F (20°C), place the included polyfoam around the incubator for better insulation.
Add water to the central humidity channel as needed. Replace the grid on top of the humidity channels and place the egg tray on top of the grid.
Replace the lid on the main body so that the rotating shaft is inserted into the open slot on the egg tray handle as shown. This ensures the egg turning mechanism will function properly.

Testing the Incubator
To avoid egg loss, it is important to test your incubator before first use.

Ensure that the rotating shaft is properly aligned, as described in the Assembly section.
Fill the humidity channels with warm water.
Note: when you get ready to use the incubator for the first time, you will not want all humidity channels to be full; this is just for testing purposes.
Plug in the incubator.
When first started, the temperature will take some time to reach the factory default temperature setting of 100°F (38°C). This may result in a Low Temperature Alert sounding from the incubator. If this occurs, you can cancel the Low Temperature Alert by pressing any button.
The default Egg Turning Interval is set to two (2) hours by default.
1. Leave the cover off so that you can observe the turning action and ensure that it is working properly.
2. Eggs should be gently rolled 45° to the right and left for ten (10) seconds, and then rolled in a random direction thereafter.

HOW TO ADJUST HUMIDITY

Adding warm water to the humidity channels controls the amount of relative humidity inside the incubator. The type of water does not matter; you can simply add water from a water bottle if you want, as long as the water is warm when you pour it into the channels.
Consult your egg supplier to determine the right humidity level for your species throughout the incubation cycle. You may want to install a hygrometer to keep an eye on humidity levels in your incubator throughout the duration of the hatching cycle. General humidity guidelines are given below, but please note that these numbers are approximate and cannot guarantee precise humidity levels.

For an approximate humidity level of 45-55%, add warm water only to the center channel as shown. This level should be maintained for the first period of your breed’s specific incubation cycle.
For an approximate humidity level of 55-65%, add warm water to the three (3) center channels as shown. This level should be maintained for the second period of the incubation cycle as the eggs develop further.
For an approximate humidity level of 65-75%, add warm water to all channels as shown. This level should be maintained for the final few days of the incubation cycle immediately prior to hatching.

HOW TO INCUBATE YOUR EGGS

Complete the setup process and adjust the temperature and humidity to your desired levels.
Place the eggs in the egg tray with their pointy sides facing down.
Close the cover and start the incubator.
Check the incubator frequently, especially in the beginning, to ensure optimal conditions.
The humidity channels will need refilling every day or two. Maintain the proper water levels with your point in the incubation cycle, increasing as needed.
When the eggs are hatching, do not open the lid until they are fully hatched.

Setup Guide

Unpack the incubator and all included accessories.
Place the incubator on a flat, stable surface away from direct sunlight and drafts.
Plug in the incubator and allow it to stabilize at the recommended temperature (99°F to 102°F) for at least 2 hours before adding eggs.
Gently place the eggs in the egg trays, ensuring they are securely positioned.
Set the desired temperature and humidity levels using the control panel.
Monitor the incubator's digital display for any alerts or adjustments needed during the incubation period.

ONCE YOUR EGGS HAVE HATCHED

Congratulations! Your chicks are now fully hatched. Allow the chicks to dry off a bit in the warmth of the incubator before moving them to a brooder unit, where they will spend their first few weeks of life. Before moving them, make sure that the brooder unit has reached an appropriate warming temperature for the young chicks.

EGG INCUBATION BASICS

Consider the Source
You should only use fertilized eggs from a reputable supplier, to ensure that they are from healthy stock and have been handled with care.

Keep it Clean
Proper hygiene can literally be a matter of life and death when it comes to hatching chicks. Clean the incubator thoroughly before placing eggs inside, and use only clean eggs for incubation. If the eggs you receive are not clean, consult with the your egg supplier, as some eggs may be suitable to gently wash, and other eggs may not be washed. Any time you open the incubator or touch the eggs, be sure to do so with clean hands.
Keep the Temperature Consistent
It is important to keep the temperature between 99.5˚F (37.5˚C) and 102˚F (38.9˚C), with as little fluctuation as possible. Keep in mind that the eggs themselves will give off heat as the embryos develop. We recommend monitoring the temperature in the incubator several times a day to make sure it doesn’t rise to unsafe levels.
Humidity is Key
Maintaining the correct level of humidity is essential to the development of the embryos. Humidity should be around 50% - 60% throughout the incubation period. During the last three (3) days of incubation, you will want to raise the humidity to 65%-75% to encourage hatching. The necessary humidity will vary by species, so be sure to check your egg supplier’s instructions.
Turn the Eggs
In order to mimic the actions of a broody hen with her eggs, it is important to turn the eggs several times a day throughout most of the incubation period. Every type of egg needs to be rotated at different intervals, so you should consult with your egg supplier or research to determine how often your eggs need to be rotated. Fortunately, your Jumbl egg incubator comes with an automatic egg rotation feature, eliminating the need to manually turn the eggs.
Guidelines for Different Species
For your convenience, we’ve provided some general guidelines on temperature and timing for different species in the chart below. Please make sure to check with your egg supplier for specific information regarding your eggs.
In general, the time to hatch for a chick is ~21 days. Smaller birds may take as few as 10-14 days; larger birds may take up to a month. Temperatures should generally range between 99°F ~ 102°F (37.2°C ~ 38.9°C), with 99.5°F (37.5°C) being largely viewed as the ideal temperature. For the last three (3) days, you should generally lower the temperature by 1-2°F, as the chicks will be putting off their own body heat. Humidity levels should generally range from 40% - 50% for the first 18 days, moving up to 65% - 75% for the final few days.

Type of Bird	Recommended Temperatures	Typical Incubation Period
Hens	99.3°F – 99.6°F (37.4°C – 37.6°C)	21 days
Pheasant	99.6°F – 100°F (37.6°C– 38°C)	23 – 27 days
Quail	99.6°F – 100°F (37.6°C– 38°C)	16 – 23 days
