Something wrong with this guy or am I paranoid???

I noticed this little guy wasn't "hanging out" with the other chicks. He was just by himself. So I kept watching and never noticed him drinking or eating. He is alot smaller then the others. I thought I better seperate him so I can keep an eye on him. I brought him to the house (our brooders are in a heated building) and set him up in a box with some food and water. I dipped his beak in the water and he drank, then I sprinkled crumbles on the floor. He is pecking but not at the food, and has not gone to the waterer on his own. As I keep watching him, he is going in circles and chirping. Could he be blind? Is he blind and not able to see where the food and waterer are? I am wondering if he is smaller then the rest because he hasn't been getting food and water the past couple of days.
He will also go in circles and fall over from losing his balance, but he isn't falling constantly. Is he making himself dizzy? Is he just the runt and I am paranoid? Or is something wrong with him? Sick or otherwise?

He is chirping but not all the time. When I brought him into the house I had him under my shirt to keep him warm and he didn't chirp until I put him in the box.
He is getting vitamin water and electrolytes.
He was hatching on monday, so 4 days old.

 

I really am thinking he is blind. He walks into the walls (on the box) and then turns around and walks into another. He walked right into the waterer and then he did drink on his own, but his feet were in there. He also has no visual reflexes. With the other chicks when you reach to pick one up they will run, he just sits. We put our finger in front of his face, quickly to see if he would react and nothing. Now I am wondering if he will be lost without the others. Like maybe he would follow their chirp to find the food.
We live out in the middle of no mans land, no pet store nearby for about 70 miles. Not one that would carry formula anyways. I do have KMR, which is kitten formula and also have syringes. Would KMR hurt?
Could I mash the crumbles very fine and add milk?water? kmr? and syringe it to him that way?

 

I took some crumbles and mixed some water with vitamins and electrolytes in it and let it mush the crumbles a bit. I put him on the plate and kept moving the food around on the plate until he would peck and get food. Finally he just kept pecking and pecking and eating and eating. So I let him do it til he was done on his own. He is now fast asleep in the box. How often should I do this with the food? I will mix fresh each time on a new plate. Hope this works.
