Breeding Chinchillas


Puberty Chinchillas

The female reaches puberty at the age of about 7 months and retains it until 12 years. However, most often it is up to 8. The male matures earlier, somewhere around 6 months of life. In a male having sexual activity, about 22 × 15 mm eggs are felt through the abdominal membranes. Throughout the whole year, they have the products of thoroughbreds. Sexual activity may show certain seasonal variations.


Female estrus occurs repeatedly throughout the whole year with a slight increase in sex drive in the months of November to May. At this time, the highest probability of effective coverage. The length of the sexual cycle is from 30 to 50 days (41 on average), and estrus lasts from 2 to 4 days. Often before the onset of estrus, a slight swelling and redness of the vagina occurs. Its openness, which continues in some females up to 8-10 days, indicates a real estrus. In the estrus phase, egg vesicles mature in the ovaries. The maximum number of offspring in one litter reaches 4 pieces. On average, only 2 babies are born. Chinchillas are low-fertile. Rodents. From June to October, the frequency of estrus onset decreases or it has a mild course.

Breeding Chinchillas


Basically, in permanent pairs you need to combine animals at the age of about 6 months. Unless we acquired the younger ones, and from the very beginning the couple was brought up together. If we had one chinchilla, and then, after a certain time, allowed another, what then? When combined, it is good if the male is 2 months older than the female. When combined, in general, it all depends on the female, which is always more aggressive and attacks the male. The male, more often than not, makes no attempt to defend himself and escapes, until he is completely exhausted. It is recommended that pairs be combined during enhanced sexual activity and in the morning, when chinchillas are still sleepy and less mobile, and therefore less aggressive. It is better if the female is allowed into the cage to the male, where she does not feel so confident. Nevertheless, in such a situation, the female sometimes shows aggression in her partner. There are several ways to teach animals to each other. You can let out a matching pair to freely run around the room. In this case, there is little risk of a brawl, and the animals have a chance to get to know each other. It is necessary to remember the dangers that can be encountered on such a “run” or what harm they can cause (see the section ‘”Control run-out”). It would be better if you divide the cage into 2 parts with a wire mesh and run one animal in each of them. The partition allows them to recognize the smell of each other and at the same time eliminates the struggle. After 12 hours, you need to remove the grid and a few more hours to control the behavior of animals. If the partner will continue to be aggressive, be sure to again put the grid on the next 12 hours. The most effective combination method used by livestock breeders with many years of experience is to place the pair to be combined for several hours in a special combination box. Its dimensions are 30x30x15 cm. Here the animals are forced to be close to each other and at the same time have very limited opportunities for fighting. It is necessary, however, to monitor if the weight sometimes reaches it, then the intervention of a guardian is mandatory. After we put the chinchillas in a cage for constant maintenance, we need some more time to watch them. If they sniff each other, rub their chins on the floor and are peaceful, then they can be safely left together. We can be sure that they accepted each other and the couple got close.

The case most often occurs at night and, of course, only when the female is in heat and she is with an active sexual partner. It lasts several seconds, during which the male introduces about 130 million sperm into the vagina of the female in 0.4 ml of sperm. Immediately after mating, the vaginal opening is open, the hair around it is wet, and at the bottom of the cell are torn hair and a chop removed from the vagina. It resembles a wrinkled spray can 1.5 cm long, filled with a white mixture and has a sharp specific smell.


Chinchilla has a long pregnancy. On average, it lasts 111 days and up to 60 days is almost invisible. After this time, the nipples, previously white and soft, harden, increase and become red. The appetite of the expectant mother increases and her mobility decreases. A pregnant female should be handled especially carefully. She can not be disturbed, unexpectedly and carelessly grabbed, as this can lead to a miscarriage. Proper nutrition is very important. Eaten food should contain all the necessary elements to maintain good condition of the female. This is very important at this time. She feeds not only her body, but also her babies. Some females, especially those that give birth for the first time, before or during lambing, do not tolerate the partner with whom they previously lived in harmony. In the first case (before lambing) you need to wean the male. It will be possible to let him into the cage later, after raising the offspring. The second case, unfortunately, most often ends tragically for newborns and the male. Chinchillas come to light most often between five and nine in the morning, and then not in the lanterns, but on the litter.

The immediate messengers of this event are sweat protruding on the nose and abdomen and a clear fluid leaking from the vagina. Now babies are born, whom mom helps with her forepaws and teeth, as well as a place. In the litter, mainly 2 babies. Each of them weighs from 30 to 70 g. They are born covered with wool, with open eyes and already having 12 teeth – 8 molars and 4 incisors.

The most difficult period of life of the suckers is the first 14 days, when the kids have to adapt to new environmental conditions. A lactating female should not be stressed, as this may reduce lactation. It is not necessary to take it out of the cage, or transfer it to another one, either with the kids. It is also good not to change the litter for at least 10 days after giving birth. The female has 6 nipples, 3 on each side, however, only two milk are produced. Kids suck mother lying under her on her back. A sufficient amount of milk is indicated by their rounded tummies and calm behavior during feeding. If its shortage occurs, the suckers fight among themselves for access to the nipples, mutilating each other, and the annoyed female runs away about them. Their tummies are then sunken. It may also happen that a mother, weakened by lambing or disease, dies. What to do then? Anyway, in the case of a small amount of milk from the mother, that at her death, it is necessary to take piece feeding. The duties of the mother are then taken by the guardian. Underfed or orphaned babies are given a mixture of powdered milk diluted with boiled water (as for infants) with the addition of a thick broth of oatmeal in a ratio of 1: 1. This mixture should have a temperature of about 37 ° C. You need to take the sucker in an upright position in your hand and very slowly let a few drops of milk into the muzzle using a pipette. During the first 5 days of life, feeding should be carried out after 2-3 hours, then after 4-7. After feeding, it is useful to massage his abdomen lightly. This replaces his licking by the mother and improves digestion. A healthy chinchilla is satisfied, eats food well, twists its tail and is very mobile.


After a week of life, the chinchilla begins to eat regular food on its own. However, in the future, mother’s milk is their main product. Therefore, small chinchillas must be with their mother for at least 45 days, and if the female was not fertilized immediately after giving birth, it is advisable that they be with her for up to 60 days) days. In the initial period of life, the offspring grows rapidly. During the first month, with the right blink, the chinchilla increases its weight three times. In the second month, the pace somewhat decreases – a double weight gain sets in. After that, it can already be separated from the mother. After the next day of the month, that is, about 120 days of life, the chinchilla digestion system adapts to the digestion of exclusively ordinary (constant) food. This is another period of life that is dangerous for them, requiring the breeder to carefully observe the basics of good nutrition. It’s best to give granulated feed and good quality hay and ‘time. Gradually and carefully, they need to be trained in green fodder: alfalfa, common thistle, and dandelion medicine! Tom, etc. Young people will be very willing to eat the young buds of an apple tree or the glacial buds.

Breeding Chinchillas


The fifth month of chinchilla life begins. In large quantities, sex hormones begin to be produced. Chinchillas enter puberty. It is necessary to find out their gender and, if there is a difference, to divide. This will avoid premature mating and closely related breeding. Further, both sexes, although not so fast, grow and develop, gain weight at the same pace. This situation lasts up to 8 months of life. After this time, the female grows more intensively, which finally exceeds the male in mass and size. At the age of 18 months they are already fully developed physically. If you continue to gain weight, then this is caused by the deposition of layers of fat.

It is worth remembering

When the chinchillas become completely independent and adapt to eating constant food, and we have no desire or cannot keep them in the house, we need to find someone who wants to purchase them. At the age of 5-6 months, it will be best for them to adapt to the new environment, to new conditions and naturally at this time they are best combined in pairs. When giving away chinchillas, we must inform their new guardian what they were eating before. If they were fed with a self-prepared mixture, then together with the wards we give back a bag of this mixture so that the animals can gradually get used to the new food.
