From an animal help website:
Baby rabbits should be fed Kitten Milk Replacer (KMR), which you canbuy at pet stores, or sometimes even a local veterinarian's office.Unless you are familiar with and skilled at tube feeding babies, use aneye dropper or sterile oral syringe, which can be purchased at mostpharmacies.
Feed baby rabbits no more than twice a day. Baby rabbits normally feedonly ONCE a day, but you're not mama and the KMR is not as caloric asrabbit milk---so if baby does not take in the total amount quoted belowin one feeding, you may split the feedings in half, AM/PM - but no morefrequently as it can cause severe gastrointestinal distress.Overfeeding is a leading cause of death in infant rabbits.
Newborn
5 cc KMR plus 1/2cc acidophilus
1 week old
10-15 cc KMR plus 1/2cc acidophilus
2 week old
26-30 cc KMR Plus 1 acidophilus
3 AND 4 weeks old until weaned
30 cc KMR plus 1cc acidophilus (You may wean at 4 weeks of age)
Baby rabbits feed from their mothers while lying on their backs. Youmay loosely wrap baby in a soft face cloth or hand towel and lay it onyour lap or in the crook of your arm. If bunny will NOT eat this way,of course, do the best you can. It is ABSOLUTELY CRUCIAL to let thebaby eat at it's own pace---especially if it is not suckling from you(i.e. if you are using a dropper or syringe to feed it...). If yousquirt the liquid in too quickly you can aspirate (get liquid in) thelungs and the rabbit will suffocate.
After each feeding it is important to make the bunny defecate andurinate to keep the intestinal tract and urinary system runningsmoothly. Use a soft cloth or a cotton ball moistened with warm waterand gently stroke from between the bunny's front legs all the way downover the anal area until the bunny starts producing stool and urine,and keep stroking until the bunny stops. You are replicating thebehavior of the mother rabbit who would lick her young to stimulatethem to go to the bathroom (as well as to keep the nest clean). Thestool will be soft and may be varying shades of green and yellow. Besure to clean baby's mouth with a damp cloth or paper towel, so that nomilk dries in the hair.
Baby rabbit eyes open at about 10 days of age. You may startintroducing them to hay and pellets at this point, but no veggies orfruits yet. Just leave some hay and pellets in a corner of the boxwhere the babies can easily get to them. Make sure it the pellets areplain, high fiber and fresh, with no added "goodies" such as driedbanana chips or seeds. Don't ever leave a deep water dish in which ababy could drown; instead, use something shallow and rinse and fill itfrequently.
