A wild baby bunny taken into a domestic situation, for whatever reason including treatment of life-threatening injuries, has about a one percent chance of survival. Wild animals are equipped to survive on their own and in almost all cases they should either be left alone, or if they really need help, a licensed wildlife rehabilitator or veterinarian should handle it. Most vets are not licensed to treat wildlife, so you may need to call around to find a vet that can help.

A mother rabbit will only tend to her nest a couple of times a day and spend the rest of the day away from it, to prevent drawing predators to the nest. If you find a nest that looks undisturbed and the mother is nowhere in sight, that is her plan. She will be back within 24-48 hours maximum to check on and feed her babies.

If you have no other choice, or if you simply need to buy time, it may help to provide it with some hay with some real fur as bedding (perhaps from brushing your other bunnies). Real fur is especially comforting to orphaned wildlife, and it gives them the sense that they are with their mother and littermates. To keep it warm, you may also want to wrap the bunny in a small towel (with the hay and fur inside).
