Detailed Explanation of Egg Incubation Methods in Gecko Breeding
In the wild, the incubation of gecko eggs relies on natural temperature. The length of the incubation period is closely related to the ambient temperature and also closely related to how early or late the eggs are laid during the laying season. Eggs laid before July 15 that can hatch into juveniles in the same year are called same-year incubation eggs; eggs laid after July 15 of the year that cannot hatch into juveniles in the same year are called overwintering incubation eggs. The incubation period of same-year incubation eggs falls in summer and autumn, when temperatures are suitable and embryonic development is rapid. The embryonic period is 92-119 days, averaging 105.1 days, with an average accumulated temperature of 2875.65°C. The embryonic development period of overwintering eggs enters the low-temperature period of the year, and embryonic development is slow. The embryonic period is 280-315 days, averaging 297.5 days, with an average accumulated temperature of 5738.05°C. If the accumulated temperature during hibernation is excluded, the embryonic period of overwintering incubation eggs is actually 116-134 days, averaging 125 days, with an average accumulated temperature of 2961.9°C. It can thus be seen that, excluding the hibernation period, the embryonic periods and accumulated temperatures of same-year incubation eggs and overwintering incubation eggs are similar. <p>In the wild, the incubation of gecko eggs relies on natural temperature.

Experiments show that when gecko embryonic development enters the seventh day, the embryo can already be distinguished with the naked eye. There are marks on the yolk, and the appearance is dark gray. When the yolk is separated with tweezers, relatively obvious block-shaped embryos can be seen, about 4 mm in length. By the tenth day, the head can already be distinguished, and two black eye spots are clearly visible. At 50 days of embryonic development, it moves when touched. At 91 days of embryonic development, the yolk has basically disappeared or only a little remains, embryonic development is complete, and the juvenile gecko is curled up inside the eggshell.</p><p>Whether a fertilized egg can develop normally depends, apart from the internal factors of the egg itself, mainly on external environmental factors, namely temperature and humidity. The length of the incubation period is directly related to the incubation temperature. Within the temperature range for embryonic development, the incubation period is short when the temperature is high and long when the temperature is low. The temperature for embryonic development is 20-37°C. Below 20°C, embryonic development stops; at 20-25°C, embryonic development is slow; at 26-37°C, embryonic development is fast; above 38°C, embryonic development death can occur. The most suitable humidity for embryonic development is 70%-85%. Experiments prove that a relative humidity of 50%-90% is acceptable for gecko egg incubation. A relative humidity below 50% will cause fertilized eggs to lose water and affect embryonic development. Long-term relative humidity above 90% will cause fertilized eggs to mold, also affecting embryonic development. Therefore, during artificial incubation, humidity should be controlled at 70%-85%.</p>
