Ryan:
You will need to examine the babies to determine if the doe is feeding them or not. I am assuming you have put them in a nest box. Don\'t assume the doe is not feeding them just because you don\'t see her go laying in the box with the kits. Unlike dogs and cats, rabbits feed their kits sporadically and furtively. This is a self-protection behavior for the species as they do not want to attract attention to the nest. In fact, I would be concerned if the doe was sitting in the box all the time (makes for mashed babies).
Anyway, kits that are being fed, will have firm, round tummies. You will actually be able to see milk in the stomach through their translucent skin. If their tummies are thin and shriveled, they are not being fed, or are not being fed adequately.
There is mixed success in hand raising kits. Following is one of several recipies out there for orphan bunny formula...
Formula for raising orphan kits
1 Cup whole cow’s milk
3 egg yolks
1 Tbsp. corn oil
1/8 tsp salt
1 or 2 drops baby kitten or rabbit vitamins
Mix well but do not whip
Feed warm, fresh formula only. Feed kits twice daily and let them eat as much as they will. Feed with a syringe, eye dropper or doll bottle. Throw away any unused portion after 8 hours.
It is important to stimulate urination at each feeding by using a damp cotton ball to wipe the genital area. This mimics the dam cleaning the kit and should cause urination.
Important: Do not over-handle kits or try to feed too much, too frequently. Initially feed a very small amount every four hours and gradually work up to twice daily feedings (morning and night) when the kits seem to be eating well.
The greatest dangers to watch for are aspiration (forcing liquids too fast and causing fluid to enter the lungs), pneumonia (a result of aspiration), hypothermia (low body heat), and diarrhea (often caused by overfeeding or bacterial infections).
Continue the bottle feedings until kits are five weeks old. At three weeks, provide access to water (preferably through a hanging waterer), and pellets mixed with about 20% uncooked old-fashioned oatmeal.
Good luck.
