Duck Egg Incubator with Adjustable Trays Supports Large and Mixed Eggs

Quick Take: Large or mixed batches are harder to set because eggs differ in size and weight. Adjustable trays let you set spacing and turning angle so eggs do not collide and air can circulate. Use a bright candler to check on day 7 and day 14, keep temperature near 37.5°C (99.5°F), and manage humidity—about 50–60% during incubation and higher in the final days. Ducks typically take ~28 days to hatch; many geese take about 30–35 days.

Key Takeaways

• Adjustable trays help prevent collisions and allow proper airflow by setting consistent spacing for different egg sizes.

• Use the built‑in candler around day 7 and day 14 to confirm normal development; promptly remove clear or blood‑ring eggs.

• Keep temperature near 37.5°C (99.5°F). Manage humidity around 50–60% during incubation and increase in the last days for hatch.

• Mark eggs with a pencil (X/O) so you can confirm turning without handling for long; aim for brief checks (<60 seconds).

• Clean and dry trays and surfaces after each batch to reduce contamination and keep sensors accurate.

Ranges & Rationale

Source notes: Ranges reflect widely used husbandry handbooks, agricultural extension materials, and incubator manuals. Calibrate instruments at egg height, select intact clean eggs, and keep equipment clean between batches.

Adjustable Trays in Duck Egg Incubator

Why Adjustable Trays Matter

You face many challenges when you try to hatch large eggs or mix duck and goose eggs in a duck egg incubator. Standard trays often do not fit these eggs well. Eggs may touch each other, causing cracks or uneven heating. Adjustable trays solve these problems by letting you change the spacing and angle for each egg.

• Adjustable trays help you avoid collisions between eggs.

• You can set the right turning angle for each egg size.

• Proper spacing allows air to move around each egg.

• You reduce the risk of breakage during the incubation process.

• You make sure each egg gets even warmth and humidity.

Duck eggs need about 28 days to hatch. Goose eggs may need up to 35 days. Both types are larger and heavier than chicken eggs. Adjustable trays support their weight and keep them safe. You can clean these trays easily, which helps keep your duck egg incubator working well.

Tip: Place eggs with the pointed end down and leave space between each one. This helps air flow and makes turning easier.

Benefits for Large and Mixed Eggs

Adjustable trays let you fit duck and goose eggs in the same incubator by changing slot width and spacing. This reduces the need for separate machines and keeps handling simple.

• Candle around day 7 and day 14 to verify growth, and adjust humidity using the water trays as needed. Keeping spacing stable and turning angles correct supports consistent development across egg sizes.

• Non‑slip tray surfaces help reduce knocks during loading and turning.

• Proper spacing lowers the chance of shell damage during turning.

• Less re‑traying means less handling and a simpler workflow.

• Use trolleys or carriers to move loaded trays smoothly before incubation.

You can check your eggs with a built-in candler around day 7 and day 14. This helps you see if the embryos are growing. You control humidity with water trays and set the temperature to 37.5°C for ducklings. Adjustable trays help you get more successful hatches because each egg gets the care it needs.

Note: Heavy-duty trays keep their shape during long hatching periods and high humidity. This is important for goose eggs and mixed batches.

Setting Up Automatic Incubator Machine

Setting up your automatic incubator machine helps you get good results. You can hatch duck eggs or mixed batches. Follow a few easy steps to give your eggs the right care.

Measuring and Adjusting Tray Spacing

First, measure each egg’s diameter. Use a ruler or caliper. Write down the size of your duck eggs and other eggs. Adjustable trays let you change the space for each egg.

Step-by-step guide:

1. Measure the diameter of every egg.

2. Change the tray slots so each egg fits well.

3. Make sure eggs do not touch each other.

4. Leave space for air to move around the eggs.

5. Check that trays are flat and locked in place.

Tip: Good spacing stops eggs from bumping into each other.

Aligning and Marking Eggs

Aligning and marking eggs helps you track turning. It also makes sure each egg gets even heat. Lay duck eggs flat on their sides. Use a soft pencil to mark an X on one side. Mark an O on the other side. This helps you see if the automatic incubator machine turns the eggs.

Best practices for aligning and marking:

• Lay eggs flat, not standing up.

• Mark each egg with an X and O.

• Put eggs with the pointed end a little down.

• Make sure all eggs face the same way.

Note: Marking eggs helps you spot eggs that do not turn.

Test Turning and Temperature Checks

Test the turning system and check the temperature before you start. The automatic incubator machine from this incubator uses auto turn and two motors. It rotates eggs every two hours. This keeps heat even and supports consistent development.

Checklist for testing:

• Plug in the incubator and check the power.

• Look at the egg turning device for anything stuck.

• Make sure the motor and gears move well.

• Put a temperature probe at egg height.

• Check if the temperature is right.

• Fix the temperature sensor if needed.

• Fill both water trays to set humidity.

Here is a table showing how EggBloom’s features help you:

Tip: Always test turning and temperature controls before adding eggs. This helps you avoid problems during incubation.

You can now start the incubation process. Use the built-in candler to check embryo growth on day 7 and day 14. Change humidity and temperature if needed. The automatic incubator machine will turn eggs and control climate for you.

Features of Auto Turning Egg Incubator

Auto Turn

An auto turning egg incubator turns eggs for you. The machine spins the eggs every two hours. This stops embryos from sticking to the shell. You do not have to turn eggs by hand. You can pause or start the turning with a button. This is helpful if you want to check eggs or move trays. Turning eggs often helps more duck and goose eggs hatch. If you turn eggs by hand, it may not be even. Automatic turning gives each egg the same care.

Tip: Put an X and O on each egg. This helps you see if the tray turns them.

Humidity Control and Water Trays

Humidity is important for hatching healthy eggs. The incubator has two water trays. Fill the trays with water to keep the air moist. Duck eggs need 50-60% humidity while they grow. Raise humidity to 65-80% for the last three days. Water from the trays makes the air wet. You can add water from outside the incubator. This keeps the temperature steady and helps big eggs get strong shells.

• Fill both trays if you want more humidity.

• Use one tray if you want less humidity.

• Check the water every day.

Built-in Candler

The built-in candler lets you check if eggs are growing. Shine the light into each egg on day 7 and day 14. Look for a red dot and lines inside the egg. This means the embryo is alive. Candling helps you find eggs that will not hatch. Take out eggs that are not growing to keep things clean. The candler works for duck, goose, and mixed eggs. You do not need to open the incubator to use the candler. This keeps the air and heat just right.

Note: Always candle eggs at the blunt end for the best view.

12V External Power Compatibility

The incubator can use a 12V external power source. You can use a battery if the power goes out. This keeps eggs warm and safe in places without steady power. You save energy and lower costs. The incubator does not have a backup battery inside. You get steady power and protect your eggs from losing heat.

Troubleshooting Incubating Duck Eggs

Fixing Tray Collisions

Tray collisions are one of the most common problems when incubating duck eggs. Large or mixed eggs can bump into each other if trays are not set up right. You can fix this by adjusting the tray slots and spacing.

• Move each egg so there is space between them.

• Check that trays are locked and flat.

• Use adjustable trays to fit large eggs and mixed batches.

• Make sure eggs do not touch during turning.

If you see eggs cracking or moving too much, stop the incubator and reset the tray positions. This simple step helps you avoid damage and supports successful hatches.

Adjusting Turning Angle

Turning eggs helps ducklings develop. If the turning angle is wrong, embryos may stick to the shell or get damaged. You may notice this problem with large or mixed eggs. Here are solutions for automatic incubator machines:

• Turn eggs from side to side, about a third of a turn each way.

• Avoid turning eggs end over end or spinning them 360 degrees.

• Mark eggs with an X and O to check if the tray turns them right.

• Watch the turning cycle and adjust if eggs do not move enough.

These steps help you prevent common problems and keep your eggs safe during hatching.

Managing Humidity and Ventilation

Humidity and ventilation are key for incubating duck eggs. Too little moisture can dry out eggs. Too much can cause mold. Use the dual water trays and vents in your automatic incubator for best results.

Check water trays daily. Adjust vents as eggs get closer to hatching. This helps you solve common problems with moisture and air flow.

Cleaning and Maintenance

Cleaning keeps ythis incubator working well and prevents disease. After each hatch, follow these steps:

• Vacuum dust and feathers from fans and sensors.

• Wipe sensors to keep readings accurate.

• Disinfect trays and surfaces with a mild cleaner.

• Let the incubator dry fully before storing.

Drying the incubator stops corrosion and keeps it ready for your next batch. Regular cleaning is one of the best solutions for automatic incubator care. You will see fewer common problems and better results with each hatch.
