Good luck. So sorry your little one is sick.
Personally when I can't come up with anything else that might be wrong, I try worming. Especially since I did loose a baby about here side to what looking back very well may have been coccidia but I didn't recognize it at the time. Heff (short for Heffner, he thinks he's quite the 'ladies' man) when I found him was sitting on his roost bar looking like a wrung out wash cloth. Head down, fluffed up, weak. It took me a few hours to suspect coccidia, then suddenly remembered the little pullet I had lost. A few drops of corid and support including treating the whole flock and he recovered....twice! Lucky charmed rooster, or two of his seven lives gone, no make that 3 gone. He got beat up last year by the flock master and lost use of an eye. I'll say this about Heff, he's stubborn.
Your little one is very weak so good support and a lot of crossed fingers.
