The chick is certainly a lot larger. And very sick, judging from the eyes. Fat and fluid buildup shouldn't be uniform. There should be areas where you should be able to feel the bones. Use you sense of touch, not just your eyes, to get an idea of where this chick is carrying this extra fat or fluid. Usually it would be predominantly between the legs. Either one, fat or fluid, would not be good.
Fluid would be caused by organ failure, primarily the liver. Some chicks hatch with genetic flaws, may get through their first few weeks seeming as normal as any chick, then the underdeveloped organs begin to fail. This isn't to insist that this is what's going on with this chick, but one possibility.
Chicks all peep very loudly when they are uncomfortable, in pain, cold, too hot, hungry, scared, etc. Any loud chick has an immediate issue that must be looked into.
It's also not a good idea to give chicks so many supplements, especially electrolytes. Electrolytes should be reserved for short term emergency use only. They can have long term negative effects on all chickens if used over a long period.
As a rule, commercial feed is well balanced with proper vitamins and minerals and needs no supplementing.
Let's see how the chick is in the morning.
