Red-faced egg turtles generally mature in 4-6 years, but how many years can they mature depends on the way of feeding. Red-faced egg turtles have high requirements for their living environment. If the breeders can meet their environmental requirements and ensure adequate food and nutrition, they will develop into adults faster, only about 4 years. If the environment in which they are raised does not meet their needs, and they often get sick during development, they will mature longer. If breeders want them to mature as soon as possible, they must ensure that the breeding environment is suitable.

In addition, breeders can judge whether they are mature not only by their age, but also by their size. Normally, when the male red-faced egg turtle weighs 350 grams and the female weighs 400 grams, it can reproduce. Breeders can judge by many factors such as age and weight, which will be more accurate.

After the red-faced egg turtle is produced, the breeder can take out the eggs first, put them in the incubator for 3-4 days, and then take them out for screening. If there are white rings on the eggs, they are fertilized and can be put into the incubator for hatching. Before hatching, it is necessary to disinfect the hatching environment, then spread vermiculite in the incubator and put it in a ventilated and dark place. The temperature in the incubator is kept at 30 ℃ and the humidity is 80%-90%. After waiting for a period of time, the incubation can be successful.
