The tortoise shells usually in spring and summer. At this time, the temperature is relatively high, and the turtle's metabolism is very vigorous and its growth speed is fast, so it will shell. In autumn and winter, the turtle will enter hibernation and naturally will not shell. Shelling is a normal physiological phenomenon of turtles, which shows that it will grow up. Some turtles shell into pieces, while others fall off a little. Therefore, we should pay attention to observation at ordinary times, and do a good job of hygiene after shelling.

1. Inactivity: Tortoise will become inactive during shelling. However, this is not easy to observe, because many kinds of turtles themselves are inactive, and turtles may become inactive due to illness. Therefore, it is not enough to rely solely on this point, but to observe other situations.

2, tortoise shell fragments: Since it is shelled, there must be shelled tortoise shell fragments on or around the tortoise, which look like a film and are very thin. Generally, after discovering this phenomenon, it is proved that the turtle is shelling, and the fragments should be cleaned up at this time.

3. Loss of appetite: When the tortoise shells, its appetite will also be affected. When it is time to feed, it will find that it does not eat. As long as the tortoise is healthy and is not a female to lay eggs, then not eating means it is going to shell.
