wild rabbit may be dehydrating?

Question
Due to the fact my neighbors dog attacked a rabbit nest, I found a baby rabbit hiding in my garage. I put it outside in my back yard.  It has fur but is very small 4 inches by 2 inches.  He stayed in the same place for 24 hours.  We now put it into a box, put cedar chips in, along with timothy hay, dandelion greens and clover and small bits of apple.  We tried taking a small dropper and feeding it water.  It doesnt seem to take any.  I am so worried it is going to dehyrate.  We were instructed to do this by our local pet store.  We are only planning on helping it along for a few weeks and then letting it go.  We already have a domestic bunny.  Can you help us?  Thank you in advance

Sincerely, Tricia  

Answer
Is it eating any of the food? You can put a small amount of rabbit food pellets in as well.

As far as dehydrating, if it was still in the nest, it probably was still nursing a little. Wild cottontails (which is probably what it was...does it have a white spot on the forehead? If so, it is a cottontail; if not, it might be some sort of hare...probably a Jackrabbit) generally wean their babies at 3 to 4 weeks old, so if it is well-furred, it is likely almost weaned.

Try this forumula:

1/2 Cup evaperated milk
1/2 Cup water
1 egg yolk
1 Tablespoon Corn syrup

You can use that and some water to help with hydration. Put the dropper, and put the tip in at the side of the mouth (no teeth there). Push in a mouthful, and wait until the baby swallows it. With a full mouth, it generally will have to swallow some. Also try putting a small water dish (not deep enough that it can drown in it) in, so that it can get water on its own, if it likes. If it is eating the greens, soak them in water for a few minutes before offering them the greens.
