As long as a tortoise is a good weight and healthy, and is a species which normally hibernates, there is no reason not to hibernate him. In the wild, baby tortoises will have their first hibernation at a few months old. Hibernation is an important part of the tortoise's life cycle, and is beneficial to their health.owever, in captivity, tortoises tend to grow faster and mature earlier. Females can lay eggs at around 14cm straight carapace length (SCL); however, breeding very young or very small tortoises is not to be encouraged as the female may experience difficulty in laying the eggs.
