TM,

Make sure you have another tank and the male out BEFORE she has the pups. If not they WILL mate straight away afterwards and you will have even more gerbils on your hands.

I have one 5 week old pup with his parents, mum gave birth to 2 babies on Tuesday, this is because I didn't get Dad out in time (she was a rescue who came pregnant the first time). Dad was neutered 3 weeks ago so they can live together and no more babies.

I do have homes, people for all the babies, but I will be keeping all of them, that is if both new babies make it (in the first litter there was 2 but one died).

I would be concerned that you have a sick female who still needs medical treatment who is now pregnant, it is not going to help her. When the pups are born and weaned put a male with dad and leave a female with her.
