Turtles usually lay eggs from April to August, which is their breeding period, but there may be some differences in captive turtles. Like other animals, it also has sexual maturity. Generally, turtles aged 5-7 can reproduce. If they are raised in greenhouses, it may take longer. After natural hibernation, it can promote the release of sex hormones, thus shortening the maturity time and reproducing faster.

1. Reproductive cycle: Usually turtles mature when they are 5 years old, and they can mate and reproduce when they are 7 years old, but they also need to look at their weight. Generally, the male is about 150 grams and the female is 250 grams. In the natural environment, they will lay eggs from the end of April to August, with May-July as the peak period. They can lay eggs 3-4 times a year, every time every 10-25 days, and each time they can lay 5-8 eggs.

2. Oviposition process: Turtles will choose a good acupoint before laying eggs, usually beside the roots of trees with loose soil and can prevent enemies, and then they will start digging holes, with the hole mouth about 3-4 cm and the depth of 8-9 cm. After digging, the mother turtle will lay her eggs in the hole and then cover them with soil. The whole process takes about 8 hours.

3. Young turtles shell: Turtle eggs generally turn purple after 30 days of production, turn black after 70 days, and have a hard texture, and break their shells after 80-90 days. Generally, they can enter the water and live independently after they come out of their shells.
