they ill eat on there own
Gerbil pups should remain with their mothers for at least six weeks, if not eight, even though they are weaned at week four. Gerbils still have many behaviors to learn, and separating them from mom early can lead to gerbils being aggressive and untameable.
Baby gerbils should be fed by their mother, but if this isn't possible, it is best to use kitten replacement milk (purchasable at pet retail stores). Feed them at least three times a day with an eyedropper until the gerbil is around three weeks old. Then you can alternate between Cheerios or bread soaked in the milk and the eyedropper of it to wean them to real food in the next week. Gerbils should be able to start eating seeds and gerbil mixes around 4 weeks of age.

Wild baby rabbits can eat rabbit pellets, hay and carrots when they are two weeks old. Before that you should hand feed them.
The Mother. The father will help groom, warm, and care for when the mother is busy eating, chewing or other gerbil things. If a baby is abandoned by the Mother, you will have to have a small medicine dropper and feed the baby ASAP. Then til the baby is 4-6 weeks old it will start eating solid food and water. Feed the baby every 2 hours. if not earlier. Make sure the baby has something to keep them warm. Maybe put the baby back and check on them all day by day.

6-8 weeks
You should feed it every 2 hours on powdered baby milk. After about 3 weeks add a bit of rusk to the mix to give it something more solid.
