Pregnancy normally lasts between 21-25 days but pregnancy can be delayed for as long as 43 days if the female is still feeding the current litter. Most Gerbils do not actually look pregnant until they are a few days from giving birth. Baby Gerbils are born naked, blind and totally reliant on their parents for all their needs. The average litter size is 5-6 young but anything between three and nine is normal. No, most Gerbils give birth without any problems.
Gerbils usually give birth in the early hours of the morning and labour can last for a few hours.
There are rare occasions when there can be problems with labour. The Gerbil usually shows signs of being unwell and if Veterinary treatment is not sought immediately, the Gerbil will die. Always ensure that unlimited fresh food and water are available for your Gerbil, she will need extra food so that she can feed her babies. Not unless you want to stop breeding. The male plays an active role in bringing up the young.
