A Detailed Guide to Turtle Egg Incubation Methods and Technical Points

Turtles do not incubate their eggs! After a wild turtle lays its eggs, it buries them in the sand, and under suitable temperature conditions, the turtle eggs can hatch into baby turtles on their own. So how do you incubate turtle eggs in captivity? Below, the editor will explain how to artificially incubate turtle eggs!

Making the Incubation Box

Simply put, an incubation box is a box used for incubating turtle eggs, and the placement and number of ventilation holes must be set.

1. You must find a box with a lid. Only a box with a lid can properly maintain the humidity inside the incubation box, and it is best if the lid is transparent. Why transparent? You will understand later.

2. Use a soldering iron to make a small hole in each of the four corners of the lid; these are the ventilation holes, and with that, the incubation box is ready. Remember, the more ventilation holes you make, the worse the humidity will be retained.

Alright, the turtle egg incubation box is basically complete. Now let us move on to the incubation substrate for turtle eggs!

Incubation Substrate for Turtle Eggs

1. Incubation substrate: There are many kinds of incubation substrates for turtle eggs. Some use akadama soil, and some use sand, but as far as humidity retention is concerned, vermiculite is the best choice. Whether the particles are large or small, and whether the color is dark or light, vermiculite always serves the same function.

2. Cleaning and disinfection: Wash the incubation substrate in water until the water runs clear, then put it in a microwave for 3-5 minutes. This can kill the bacteria in the vermiculite. Then soak the vermiculite in purified water for about 30 minutes (be sure to use purified water or cooled boiled water to avoid bacteria in the water).

3. Moisture control: Grab the vermiculite with your hand and squeeze out the excess water, squeezing until no more water can be squeezed out. The vermiculite should not look wet, yet it should be able to be pressed into a ball without falling apart. This step is very important. If there is not enough water, the moisture-retaining time will be short. If it is too wet, the embryo will grow too quickly in a high-temperature, high-humidity environment, the embryo will develop too large, the air inside the egg will be filled up, and the embryo will suffocate inside the egg. Death of fertilized eggs in the later stages of incubation is basically caused by this. In this way, the incubation substrate is ready.

Arranging the Incubation Box

1. Thickness of the vermiculite: Put the squeezed vermiculite into the prepared incubation box. The thickness should be about 1/2 to 2/3 of the height of the box, leaving 1/3 for placing the eggs. Converted to centimeters, 8-10 cm is about right. There is no need for it to be very thick, because the method introduced here uses bottom heating. If it is too thick, the temperature will be hard to control. Moreover, this incubation substrate is actually used to maintain humidity. When incubating snakes, only a sprayed paper towel is placed at the bottom, and as long as the temperature is maintained well, juveniles can still be hatched successfully.

2. Placement of the thermometer: Placing the thermometer is very simple. Just lay it flat on the incubation substrate, placed to one side.

3. Placement of the eggs

① Mark the laid eggs, that is, use a marker pen to make a mark on the side facing up. This mark is so that if the egg slightly rotates during development later, or is turned over due to an accident, the egg can be restored to its original position without affecting embryonic development.

② Move the eggs out horizontally and place them into the incubation box, right on top of the vermiculite, and just stabilize them. You can also bury 1/3 of each egg to keep it stable.

Finally, put the lid on, and a professional incubation box is complete.

Management During the Incubation Period

1. Methods for increasing humidity: There are two ways to increase humidity. The first is to add water to the vermiculite, and the second is to replace all the vermiculite.

① Adding water to the vermiculite: After 60 days of incubation, the humidity will have evaporated almost completely. At this time, you need to add water to the vermiculite. There are two methods. One is to use a syringe, draw in purified water, and inject the water into the vermiculite around the eggs. The other is to cover the eggs with something, then use a spray bottle to spray water onto the vermiculite. Be sure to use purified water.

② Replacing the vermiculite: Replacing all the vermiculite means preparing a new incubation box and moving the eggs into the new incubation box.

Calculating the hatching time: The hatching time should be inferable based on temperature, and generally before hatching, water droplets will appear on the eggs. At this time, you should open the incubation box frequently. As long as a juvenile has emerged, it can be taken out, so as to prevent the juvenile from crawling around in the incubation box and turning over other eggs.

Assisting difficult-to-hatch eggs: Eggs can also have difficulty hatching or be in an abnormal position. If the tail or legs emerge from the eggshell first, you must help by peeling the egg to help the juvenile hatch smoothly. If the head has been exposed for 2-3 hours and it still has not crawled out of the shell, you must peel the shell, otherwise after the amniotic fluid dries up, the eggshell will harden and the juvenile will be stuck and die inside.

Rearing and Management of Juveniles

1. Because the humidity inside the incubation box is relatively high, newly hatched juveniles must be placed in an environment with relatively high humidity once they hatch, and then you must slowly wait for the humidity to dissipate. They cannot be placed directly into a relatively dry environment, otherwise the juveniles will not adapt.

2. Generally, newly hatched juveniles can only be fed after 3 days.
