Really? OK, so what about vitamin water? Is there nowhere to read about newly hatched baby quails not eating?
Kikis concern is that it is So easy to aspirate a small bird. If you give even one drop too much(which is only like 3 total) then it would quickly and easily spill over into the part they breathe through. If hes never eaten then he doesnt know how to take the food and swallow it until they try. In my years experience hatching hundreds of eggs in small batches too often there are chicks who fail to thrive. Its caused by a vast number of issues and usually after the first three days the rest will be stable but it sounds to me like something about that chick didnt develop properly. Im sorry but i think you will loose him and you need to concentrate on the healthy babies.
