Candling are a method that you can use to check the development of tortoise eggs. Candling is a method that allow you to see inside of a tortoise egg without breaking the shell of that egg. To candle a tortoise egg, you will need to use an light source to look through the shell of the tortoise egg.
The light will allow you to see if there is a tortoise embryo growing inside of the egg. Many person use this method to determine whether a tortoise egg is fertile or if the tortoise egg is infertile. If the egg appear to be clear and yellow when you shine the light into the egg, then the egg is likely infertile.
How to Candle and Care for Tortoise Eggs
However, if you can see a network of blood vessels inside of the egg, then the egg is likely fertile. By using candling to determine if a tortoise egg is fertile, you can better manage the incubator for the tortoises. You can easily remove any infertile egg from the incubator and focus your attention on the eggs that are likely to contain embryo and develop into tortoise babies.
To candle a tortoise egg, you must work in a dark room and be careful when candling the eggs. Excessive handling of tortoise eggs can lead to the death of the embryo within the egg. When the embryo is within the egg, it takes up more space within the shell of the egg.
At the start of incubation, the embryo appears as a small mass of blood vessels. However, as the egg continues to incubate, the embryo will take the form of a large dark mass within the egg. If the interior of the egg is clear for an extended period of time, then the embryo within the egg may have stopped developing.
The incubation period for a tortoise egg can vary depending on the species of tortoise. For example, a Sulcata tortoise takes more time to develop inside of it’s shell then a Russian tortoise or a Greek tortoise. Due to the fact that each species of tortoise have different needs in regard to humidity and temperature in which they require to exist, each species of tortoise cannot be prepared with the same methods.
You must prepare the needs of the substrate for the eggs of each species of tortoise to match the requirements of that specific species, as well as the humidity levels within the enclosure must also mimic the natural environment of that species of tortoise. If the environment does not mimic that of the natural environment of the species from which the egg is sourced, the embryo within the egg may not be able to survive the process of incubation until the tortoise reaches the stage of breaking through the shell of the egg. At the end of the incubation period for the egg, there are some physical change to the tortoise egg that may be visible.
The tortoise egg may “sweat,” which is a sign of the preparation of the hatchling in regard to the process of breaking through the shell of the egg. The first sign of the tortoise breaking through the shell is the appearance of a pip, which is a small crack in the shell of the egg. During this stage, it is important to not attempt to assist the tortoise in breaking through the shell.
Should someone attempt to break the tortoise through the shell at this stage, the yolk sac of the embryo may be damaged, which is vital for the survival of the tortoise during its first few days of life. In regard to the incubation process, troubleshooting will be necessary. For instance, if mold is present on the tortoise egg, it is possible that the environment is incorrect.
If the egg collapses, it is possible that the humidity levels within the environment were too low. It is important to avoid over-moistening of the substrate within which the eggs are placed, as too much moisture can lead to the embryo in the egg being suffocated. Additionally, if the substrate becomes too dry, the dryness of the substrate may also harm the embryo.
To successfully incubate the eggs, you must maintain the balance of moisture and heat within the incubation environment, as well as continuous monitoring of those eggs through the process of candling.
