Chinchillas have a gestation period of approximately 111 days, which is relatively long compared to other rodents of similar size. During this time, the female chinchilla will gain weight and her belly will become noticeably larger. She may also become more aggressive and territorial as she prepares to give birth.
Giving birth
Chinchilla usually give birth to two or three babies, but litters of up to six have been known. The babies are born altricial, which means they are helpless and rely on their mother for survival. They weigh only about 30 grams at birth and are covered in a thin layer of fur.
Nursing
The female chinchilla will nurse her babies for several weeks. She will produce a special type of milk that is high in fat and protein, which helps the babies to grow and develop quickly. The babies will nurse frequently, and they may even suckle while the mother is eating or sleeping.
Weaning
Chinchilla babies are usually weaned by the time they are about eight weeks old. At this point, they are able to eat solid food and they no longer need to rely on their mother for milk. The mother chinchilla will typically stop nursing her babies at this time, but she may continue to care for them and protect them until they are fully independent.
Raising young
Chinchilla babies are very social creatures and they enjoy playing with each other and their mother. They will often spend time chasing each other around the cage and climbing on the walls. As they grow older, they will begin to explore their surroundings and learn how to forage for food.
Independence
Chinchilla babies are typically considered to be independent by the time they are about three months old. At this point, they are able to care for themselves and they no longer need the constant attention of their mother. They may still choose to stay with their mother and siblings for a while longer, but they will eventually leave the nest and start their own lives.
