Baby fawns go through two containers of milk a day. All goat milk or a fawn replacement milk should be used. Some Walmart stores carry goat milk; Tractor Supply stores carry a wildlife replacement milk that will include fawns on the back label.
A newborn fawn is the size of two Chihuahuas. It's important to add seven drops of lactate as well to the formula. If you have a young fawn, do not add anything solid.
When they are the size of the deer in the photos below, add some solid food to the formula such as baby rice or baby cereal. Mix it well with water until it has a pudding-like consistency. Deer love sweet tastes, and bananas are always a good source of sweetness. For older deer, you can add a banana, but be sure to beat it with a fork until it liquefies. You can put it into a blender or use a mixer and stir it up -- but make sure the banana seeds don't clog the nipple.
The hole in this nipple is too large!Also, be sure that the hole in the nipple is not too large so the liquid cannot be drunk too quickly. If they drink too fast, they will give themselves a stomachache along with having digestive problems.
Before feeding, heat up the formula. You don't want to feed deer cold formula. Then give it to the deer before everybody else eats it. (Ingrid said that as one of her cats was sampling the formula to be sure it was just right.)
Use a funnel to pour the mixture into baby bottles (two per fawn per feeding). There should be two feedings a day. Be sure to heat the liquid. It must be given very warm.
When feeding, keep the bottles high because that's how they would eat from the mother as she stands up
They go through it quickly.
You can pull and push back and forth as you feed, because that's what the mother does.
Also take a warm wet cloth and wipe the genital area to help stimulate the bowels. If they are not kept regular, they will get diarrhea or become constipated.
The deer in the photo are not that young, more like two months old. By the way, these guys are not related.
If they're older, you can chop up carrots or apples and just stick the pieces in their mouth. When deer go from formula to other foods, it's a big move.
Unless you actually see a dead doe, leave the fawn alone. Fawns are rarely orphaned. The mother will often run if you approach, and return to the fawn after you leave; the fawn can't run, and will typically freeze and try not to be seen.
Be sure to contact an animal rehabilitator promptly if you are dealing with a young fawn, because they imprint quickly, and once imprinted, are problematic to release into the wild.
