Could he have been kept away form food and water by the other chicks, sounds like they may have been picking on him if he has lost some feathers on his wings is it bloody or raw looking? you should spray with Blue kote to protect from further damage if the other chicks are doing this. Sounds like your on the right track giving him fluids with electrolytes in it. Make sure to watch and see how the others are treating him, they can do some serious damage to one not feeling well.
Good idea, and Blue kote is fairly inexpensive at TSC I think I paid 4.95 or 5.95 for a spray bottle and it last forever. Just in case you don't know, this stuff will make you and anything you are wearing purple so wear old clothes and gloves. I have Blue kote towels etc. to prove it. lol And spray outside in an area where you don't mind it getting purple if the spray gets on it. But it is awesome stuff for healing and disguising wounds. Some places carry it in a bottle with a dabber too.
