Will mother gerbils bury their babies?

Whatever you do don't touch them until they are old enough to move to another cage. Once the mother gerbil is done nursing she wont want them around and will try to harm them. When they are old enough to stop nursing move them to another cage immediately. Watch to make sure they are drinking on their own that is how you will know when the time is to change cages.

can you touch the baby gerbils when they have no fur will they die or get no fur where you touch them?

I don't think mother gerbil will harm her babies. If she is burying her babies it is most likely she is protecting them from preditors. Keep an eye on them and make sure they are all nursing. Depending on their ages i would not touch them because of human scent on the babies. When you are cleaning the cage maybe add a little less shavings until their bigger.
